Definitely closer to 4.5 stars. Of course it's pretty similar to her other books, which doesn't bother me... I love her writing and find myself addicted to every book she puts out. This series will definitely help me forget my sadness when PLL finally ends in December. As usual you've hooked me, Sara Shepard! I just love the books where you get a slow release of information and learn the characters secrets throughout. Everything builds up until you sense an explosion at the end. The ending was abrupt, even for Shepard.
