Zoe is a mum of a three year old girl Anna, happily married to surgeon Ethan and quite frankly her life could not be any better. 

Until there is a knock on the door and a thirteen year old Micah announces that his mum is missing, and Ethan is his dad. But credit to Zoe, she welcomes this boy into their home and convinces Ethan that they must look out for Micah and make sure he has a nice home. 

But quickly things start to get weird. Little incidents and Micah calling Zoe mom within 24 hours, make Zoe feel on edge and like something just isn't right with the boy and she realises that she has invited into he life someone, she knows nothing about. And when Police tell her, Micah's mum is found dead, Zoe swear she will protect her family at all costs. 

This is a quick page turner. A little predictable especially since perfect Ethan is so squeaky clean and clearly has emotional superiority and control over Zoe, even is she doesn't admit that to herself. 

Anyone that like a quick read thriller, will enjoy this book and the ending I felt was also perfect.
