Trex

By: Christyne Morrell

Narrated by: Jacob Mcnatt, Erin Ruth Walker, Maria Marquis

A thrilling mystery packed with adventure, secrets, and high-stakes danger! A boy with a cutting-edge brain implant and a reclusive girl training to be a spy must outsmart school bullies and take on a sinister corporation that’s hacking minds.

"Original, exciting, and chock-full of mysteries for the reader to unpack, Trex has all the makings of a hit."—Wesley King, #1 New York Times bestselling author of The Wizenard Series

Trex’s experimental brain implant saved his life—but it also made his life a lot harder. Now he shocks everything he touches. When his overprotective mother finally agrees to send him to a real school for sixth grade, Trex is determined to fit in.

He wasn’t counting on Mellie the Mouse. She lives in the creepiest house in Hopewell Hill, where she spends her time scowling, lurking, ignoring bullies, and training to be a spy. Mellie is convinced she saw lightning shoot from Trex’s fingertips, and she is Very Suspicious.

And she should be . . . but not of Trex. Someone mysterious is lurking in the shadows . . . someone who knows a dangerous secret.
