In sight not see
black light not be

This is the curious instruction that comes with the Eye of Know, the possibly powerful crystal amulet that Montgomery Sole buys online for $5.99. It’s also the next topic of discussion at Mystery Club (members: Monty and her two best friends, Thomas and Naoki), dedicated to the exploration of the strange and unexplained.

When Monty wears the Eye of Know, strange things happen, all targeted at people she despises. Maybe it will help Monty take down her newest enemy, a preacher who has come to save her town from so-called sinners—sinners like Monty’s moms. Or will its mysterious powers mean the end of the friendships Monty cherishes most?

Mariko Tamaki has created a thoughtful, funny, and painfully honest story about family, religion, ignorance, and other unsolved high school mysteries.
