4.5 Stars!!! 
 One of the things that I love most about Penny's books is that they are completely unpredictable. Even after reading the 3 books leading up to this one I had no idea how it was going to affect me. 
 True to form, Penny's quirky style shines through, but the heartbreak that I felt in this one made me fall hard. I absolutely ADORED Alex's story. 
 I can't wait to see what's waiting next in this series! Back to the nerd cave...
