Suspense with a touch of romance. Each chapter is from the point of view of one of the three main characters, and sometimes the chapter is from their past, which allows you more insight into each character and gives a reason for certain behaviors from them.
Although the format is different than I normally read, I found the book to be easy to follow. It has great character interaction, and a plot that will keep you on your toes.
A great read for all those interested in suspense or mystery/thriller type books.
