### **Chapter 1: Beneath the River’s Skin**

There are three kinds of secrets in the world: the ones you keep from your friends, the ones you keep from your enemies, and the ones you keep from yourself.

I’d always thought my secret belonged in the first or maybe the third category. I was half-right—I’d never dreamed my secret would thunder through the living room, trailing muddy footprints, with my mother standing slack-jawed by the staircase.

My name is Theo, and I can turn into a spinosaurus.

Not the flat-footed, Godzilla-mouthed, “Jurassic Park” beast—no, I become something that science tells me is accurate: low-slung, crocodilian, nostrils high on my snout, sail arching like a riverbank sunrise. Whenever stress prickles at my skin or rivers call me by name, I shift. And I am not alone: my friends shift too.

But nobody knows. Not our parents, not teachers, not normal humans. Until today.

It started innocently enough—Max and Jamie dared me to race the autumn flood, and I could never resist a challenge. We ducked beneath the old steel bridge, each of us waiting until the dog-walkers were out of sight, and then we let go.

Jamie went first: fur rippling, her face lengthening into a bushy-tailed fox. Max followed, bones grinding, neck stretching into the hulking, dappled form of a moose. My turn—claws erupted from my fingers, jaw stretching into an endless snout, scales itching into place, the world growing distant and deliciously vast.

I hit the water in an explosion of spray, my tail slicing through the current. I was home.

What I didn’t realize, tangled in the pleasures of warm mud and cool water, was that Mom had chosen that exact bridge for her afternoon walk. That she’d dropped her keys and leaned over the rail, only to see my sail flashing red and cream beneath the surface.

That night, dinner was silent. I had mud on my socks, and the old smell of earth clung to me like a secret I couldn’t wash away.

Afterward, she cornered me in the laundry room, her face pale. “Theo. I saw. I saw you. What are you?”

I could’ve lied. But something wild in me, something scaly and primeval, gazed up and down the eons and said, “Mom, I’m…not like other kids.”

### **Chapter 2: The Invitation**

Confessing wasn’t the hard part. The hard part was the waiting: the buffered silence, the slow, careful internet searches I overheard from the hallway, and the text from a number I didn’t recognize.

*We know. Your child is safe. Tomorrow: The Leif Institute, 10am. Directions attached.*

I showed it to my friends. Jamie bared her fox-teeth and hissed, “It’s a trap.”

Max only said, “We’re going—if they know about you, they know about us too.”

The next day, a hush settled over our minivan as we wound through pine forests toward the dark-shingled campus. Mom’s knuckles were white on the wheel. My heart raced, half-forgotten muscles itching in my shoulders as if I could simply grow a sail and glide away.

We pulled through iron gates beneath a sign: *Leif Institute for Gifted Shifters*.

My mom strode in first, shielding me with her arm. Immediately, a tall, elegant man approached. His eyes had a strange orange ring. He handed my mom a stack of paperwork and a rich, golden leaf.

“To enter, the child must do it willingly,” he intoned.

I placed my palm on the leaf.

The whole world seemed to shift. Suddenly, ordinary reality peeled back—revealing an immense campus humming with energy. Children ran in every direction, some scaling walls like lizards, some sprouting bear-claws before laughing teachers. I saw Jamie’s shock; Max’s awe.

My mom hugged me so tightly I swear my sail almost unfurled.

### **Chapter 3: Orientation**

The first thing they taught us was control.

"It's not enough to become the animal," insisted Dr. Chau, our transformation mentor and—if rumors were true—a harpy eagle shifter. "You must wield it. Own it. Shape it, rather than letting it shape you."

Shifting in front of strangers was strange at first. Jamie flicked her fox-ears nervously; Max practiced dunking his antlers in giant water troughs. When my turn came, I wanted to shrink, but Dr. Chau's gentle reminders echoed in my skull: *power and purpose, purpose and pride.*

I let go. My form crashed and expanded; my arms became oar-like, my tail lashed, and I felt the court’s artificial stream calling me. Beneath glass ceilings, under curious eyes, I swam like a river ghost.

I didn't expect applause. I didn't expect envy, either—pale, nervous Cato from our dorm edged up to me afterward.

“You’re a…is that a spinosaurus? Like the new papers say, with the paddle tail and everything?”

I nodded, bashful.

“Dude. That’s so much cooler than being a box turtle.”

I grinned, real connection sparking—the first outside Max and Jamie to treat me as something more than a monster.

### **Chapter 4: Lessons in Difference**

Classes here were nothing like at home. We studied animal psychology *and* algebra, learned about shifting genetics, diets, and the responsibility to hide from the broader world.

The counselors said most shifters inherited their forms from ancestral lineages: the wild boar grandmothers, the bear uncles, the wolfish parents. But sometimes, weird things happened. Dr. Chau called us "throwbacks." That meant me, the ancient, sail-backed swimmer; it explained why, out of Max the moose-family and Jamie the fox-folk and their shapes, mine felt so…off the evolutionary rails.

I wasn’t just different from humans. I was different from shifters, too.

“Embrace it,” said Dr. Chau quietly, one afternoon as I eyed the other kids’ effortless transitions. “Your strength is unique. You can do things even I can’t imagine.”

The Institute’s river system, engineered for aquatic shifters, became my escape. Some days I’d slip into the current, scales flashing, immense teeth snatching synthetic fish. Max, on a dare, let me tow him downstream—he said it was like skiing behind a speedboat.

Jamie, always fidgety, preferred to stalk around me, darting out of the reeds and challenging me to games of chase.

We learned secrets from each other. Jamie could squeeze into impossibly small places; Max could run down deer. Me? I could vanish into the river, invisible to nearly everyone until the last tumultuous splash.

### **Chapter 5: Discovery**

All fun and games, until the accident.

On a blustery night, the river banks swelled. I led the group farther downstream than usual. There was a spillway, and next to it, tangled in a crumpled fence, a whitetail deer—shivering, leg caught.

It wasn’t a shifter, just an animal.

Max panicked, stamping. Jamie wanted to rush in. Something old and primal took hold of me; I became the spinosaurus fully, glassy-eyed with blood and panic, herding my friends to safety while pulling at the fence with jaws like scimitars.

By the time the teacher-guards arrived, we'd freed the deer, but not before I lay, gasping, sides heaving, aware that half a dozen adults had watched the whole thing—and not just teachers. Parents. My mom among them.

Against the odds, she was…proud.

They wrapped me in blankets. Told my friends and me that we'd acted with courage and wisdom. The deer, safe; the spillway dangerous, but we had done well.

It was something new, seeing my “difference” not as a threat or a burden, but as a tool, a gift.

### **Chapter 6: The New Normal**

I write this now from the Institute’s stone steps, Jamie curled in a fox-pile beside me, Max snoring, half-morphed, under a pine.

Classes are easier now. The secrecy is, too—because secrecy isn't loneliness anymore. Every day, we meet someone whose animal is stranger, stronger, or simply odd: pangolin kids, clouded leopards, an ancient dire wolf or two. There's even a girl with trilobite scales who claims to see backward through time.

I see my mom every Sunday. She brings cookies and asks about “shifter math”—how do you calculate body mass when you have both gills and lungs? We laugh about it. We talk, really talk.

Am I still afraid? Sometimes. The world is big and confusing, full of secrets worth keeping.

But I have friends. I have teachers. I have rivers that call my name.

And when the scales grow restless, I know that I can step outside, into the current, and be exactly what I am: a spirit animal with a tail like thunder, fangs like hope, and a heart that bridges the eons.
