Help me find Imp!

[FlourishandBlotts]

I've been wanting to read this book, im certain it's called Imp, about a boy whos mother keeps him locked in the basement. That's all i know about it. It's one of the only books my mom has read and liked so am intrigued but cannot find the book anywhere! Can anybody help? X

Is it a children's book or an adult's?

Adults x
