The Mostly Invisible Boy (Casey Grimes #1)

Name: The Mostly Invisible Boy
Author: A. J. Vanderhorst
Pages: 307
Buy Link: amazon

Synopsis: This “wildly imaginative” (Book Pipeline) “splendid conception” (Kirkus) from upstart author AJ Vanderhorst celebrates the transformative power of courage, tenacity and a little skill with a battle-axe. Set in an alternate USA where monsters prowl, this debut novel is told from the perspective of mostly-invisible-but-still-hopeful Casey Grimes.

Eleven-year-old Casey is stubbornly friendly, but he’s eternally the new kid at Vintage Woods Middle School. Students look right through him—and they’re not faking. Casey doesn’t know why he’s mostly-invisible, but when he scales a colossal oak, he discovers a fortress in its branches. The forgotten sentry tree marks the border between his safe, suburban life and a fierce frontier.

Casey and his little sister Gloria infiltrate Sylvan Woods, a secret forest society devoted to ancient, wild things. Sky-high footpaths. Survival sewing. Monster control. Shockingly, people here actually see Casey—but being seen isn’t enough. He wants to belong.

Keeping his identity hidden–while struggling to prove he fits–is hard enough, but Butcher Beasts have returned to Sylvan Woods after a hundred years. Trickery is under siege. As the monsters close in, and the fearsome Sylvan Watch hunts Casey down, he and his newfound friends must unearth abandoned magic, buried at the forest’s roots…or be devoured along with everyone else, Sylvans and civilians alike.

A fast-paced middle grade fantasy/adventure book with all the monsters kids could ever hope for.

About the Author:

A.J. Vanderhorst

AJ Vanderhorst has had many jobs, including journalist, paramedic, escape artist, and baby whisperer. One time in fifth grade, he built a traffic-stopping fort in a huge oak tree, using only branches and imagination, and slept there for a week.

Now he and his wife live in a woodsy house with their proteges and a ridiculous number of pets, including a turtle with a taste for human toes. This makes AJ an expert on wild, dangerous things—invisibility spells, butcher beasts, hungry kids, you get the idea.

He is the only author in the world who enjoys pickup basketball and enormous bonfires, preferably not at the same time. He and his family have drawn up several blueprints for their future tree castle. Visit AJ online at
