well if you like a dark thriller with a literate bent and clever twists and turns this is excellent. the first book i've read in ages that i'd say was a page turner and i couldn't put down.  

bad things happen in 3's right? or does it just seem that way?

here we have female protagonists attempting to decipher their history and the events surrounding their trauma, and each character is nested inside one another individual story, it's a great read and sam ripley is an intelligent writer that knows what his reader needs, to be challenged, surprised and entertained.
