Corvus Academy is a place where the impossible becomes possible. It's a secret boarding school filled with the world's most unsociable geniuses. Until Greta arrives. Then it's also filled with . . . murders!

Greta Nilsen is in the middle of a boring maths lesson when she's told by a stranger in a fancy suit that she has a place at Corvus Academy.

There are only three problems with this:
1) Greta never applied to Corvus Academy
2) Greta definitely isn't a genius (or in any way unsociable)
3) There's no evidence that Corvus Academy exists

But the opportunity for adventure is too good to miss . . . A decision Greta soon regrets, when her non-genius secret becomes harder and harder to keep, shortly followed by the death of a teacher in circumstances that make her look VERY guilty.

How can totally average Greta Nilsen hope to solve a murder, clear her name and stay undercover in a place she clearly doesn't belong?

This hugely inventive murder mystery is from the NYT bestselling author of How to Solve Your Own Murder. Perfect for fans of Murder Most Unladylike, Crookhaven and Wednesday.
