Oh a thriller! Sandie Jones does it again. The Half Sister is exactly what I needed. Did it keep me up all night to figure out the ending? No. But, it did have me thinking about it nonstop until I got to the ending. This is a family drama that makes you question everything and really wonder who you can believe and who is really telling the truth. This is a book where everything starts fine, nothing seems wrong, almost too good. And so it proved that things can be too good to be true. The secondary characters were some of my favorite parts. I love a book that shows one person or one secret can really blow something up. Sandie Jones is such a thriller genius and really knows how to keep you guessing til the end.
