The Mostly Invisible Boy (Casey Grimes #1) + Trickery School (#2) Paperback Bundle

The first two books in the thrilling Casey Grimes series—in a discounted bundle.

The Mostly Invisible Boy (#1) - Need friends? Try fighting monsters.

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.

Trickery School (#2) - Classes have begun. Please don't die.

In this "gripping fantasy adventure" (The Wishing Shelf Book Awards), Casey Grimes begins his studies at Trickery School, one of America's premier monster-control academies. But classes like Extreme Climbing and Land Creature Defense are the least of his worries. He realizes a mysterious enemy is after him—more cunning than a Bog Creep or Hyena Toad. And this secret adversary is playing for keeps.
