The Half Sister is a very gripping story full of suspense and family drama. A girl claiming to be Kate and Lauren's half sister shows up at the very beginning of the story and from there the story twists and bends making you wonder what's the truth and what is this girl's true intentions. I found it all very compelling and couldn't stop reading until I found out the truth for myself. I really liked the fast pace and think the story pretty much led where I was expecting, but still throughly enjoyed the journey to get there. I was a bit confused still at the end of the story about a room found in Jess's place, but other than that the other lingering questions just add to the suspenseful feeling of the story. Overall I think it was a great read and look forward to reading more books by Sandie Jones.
