Query: What was it all about?

I kept waiting to find out what the horrible secret in Cate's past was to cause her bizarre behavior. The ending - although a surprise - came at you way too fast - and rather like someone who said "okay I think I'll choose so and so as the culprit." The romance aspect had teenager written all over it - both with Cate and her friend. And the overall end - give me a break - that doesn't happen in "real" life. There really was no "mystery" in the real sense - you felt the murder was just a secondary consideration.What a waste of time! I could have used the time I wasted on reading the book to do something really productive - like watch my grass grow!
