Leo Marshall just wanted to open his locker.
Instead, he found a note.
Then another.
Then about a hundred more.
Suddenly, Leo is at the centre of the strangest mystery his school has ever seen. Who's leaving the notes? Why are they watching? And how did Leo become "the cutest kid in Year Five" without agreeing to it?
With his space-obsessed brother, a group of very serious friends, and a school buzzing with rumours, Leo sets out to solve the mystery-only to discover that sometimes the truth is more awkward (and funnier) than you expect.
Locker 217 is a laugh-out-loud middle-grade story about lockers, secrets, first crushes, and what happens when being noticed is both embarrassing and kind of awesome.
