Don't Trust the Kid in the Mirror

By Jeremy Kelly

John is suddenly polite, neat, and eats his broccoli. That's how Jack knows.

Auntie Jess's creaky Victorian house has an attic, and the attic has a tall silver mirror under a sheet. One midnight, John touches the glass. The next morning he says please, parts his hair on the wrong side, and writes his name backward.

Mom and Dad think he's finally growing up. Jack thinks the real John is trapped on the other side of the mirror. With help from Amelia, Jack has until sunrise on the third day to get his brother back, or the kid in the mirror stays forever.

Kelly Brothers Rule #1: Never leave your brother behind.

The Kelly Brothers Mysteries are spooky, funny, fast-moving monster mysteries for readers 8-12, told by eleven-year-old Jack Kelly, who investigates with a notebook, a four-year-old brother, and a goldendoodle puppy named Julk. Every case is real. Every monster is real. And every book ends with the brothers still together.
