In The Blood by Lisa Unger
The Silent Wife by A. S. A. Harrison
Empty Mansions by Bill Dedman
Frog Music by Emma Donoghue
It's hard to say which has been my very favorite, but I will say that In the Blood and The Silent Wife both had moments where I had to put the book down because I was so mad at the character or what was revealed was such a surprise and I had to rethink bits and pieces and put them together.
