Catherine is a party girl who enjoys the single lifestyle. When she meets Lee, she is immediately attracted to him and they strike up a relationship. Lee seems wonderful and her friends are all envious of their relationship. But gradually, Catherine starts to find the relationship claustrophobic. Lee starts questioning her about her movements, spying on her, trying to control her. We know from the book's prologue that things are going to go very wrong, but it's not clear exactly how it's going to happen.

Meanwhile in a parallel storyline, we are also following a vastly different Catherine some four years down the track - one who is crippled by anxiety and OCD, finds it impossible to open up to anyone and who has clearly been through a horrific experience. A new man has come into her life, but can she trust him? And is she safe from Lee?

What's great about this book is the rising tension throughout. There are some small twists and surprises along the way, but overall it's evident that we are building towards some kind of climax - it's just not sure what that will be. The suspense grew so strong that I literally couldn't put it down for the final 100 pages. Up until that point though, I did feel that it was a little too drawn out. Having said that, I liked the way the gradual shifts in Lee and Catherine's relationship - and her gradual recovery in the later story - were portrayed.

If you enjoyed this, I strongly recommend The Bed I Made, another (equally tense) book about a relationship gone sour.
