This is the second book in an exciting new mystery series from the same writer as Pretty Little Liars! One of my favourite parts about this book is the mystery is constantly changing and twisting so it constantly grips you! This series of books definitely fills the gap that Pretty Little Liars has left! I really love the cover of this book too as it is so bright and instantly made me want to read it! I really enjoyed the writing style in this book and although it was a short read it was action packed and so hard to put down that I read it all in a single day! The only down side of this book is although it is claimed it can be read as a standalone, a lot of this investigation wouldn't make sense if you haven't read the first!
