Force of Nature- Sue Cook

After three failed attempts at IVF, Jenny and Mark Elfick are overjoyed when their fourth attempt is a success. The arrival of their beautiful daughter, Chloe, marks the beginning of a new chapter in their lives and as they watch Chloe grow their happiness seems complete. When Chloe is two years old, however, Mark suddenly starts behaving very strangely and Jenny fears he is having an affair. But nothing can prepare her for the shattering truth as to why Mark is being so secretive. It is a revelation that threatens to destroy someone else's family as well as their own.

This is Sue Cook's (former radio and tv broadcaster) 2nd novel, and I really was hooked from the start. A heartfelt story, as two families lives are changed for ever, when a secret is let loose. A great read!
