IQ

The mystery itself was great. It had interesting twists that kept me guessing until the end. But I disliked the characters (not IQ though), so it was hard for me to care about them and keep reading. I don't think I'll continue reading this series just because I'm afraid all the characters will be like the ones in this book.

I won this book through GoodReads and I thank to publishers for providing me this copy. My review isn't influenced by this fact.
