I loved All Fall Down. The short summery on the back really does explain the plot of the book quite well: "Grace Blakely is absolutely certain of three things: 1. She is not crazy. 2. Her mother was murdered. 3. Someday she is going to find the killer and make him pay." But the book is also a lot more. It's wonderfully written and made me cry, with enchanting characters, and a protagonist who just wants to be normal - but how can you be normal when you saw your mother murdered and no one believes you, and you live on Embassy Row - where a fight with the neighbours means World War Three - especially when you just met the man you saw the night your mother died and you heard him say he's going to kill again.
I have been an Ally Carter fan for years and this book did not disappoint. Unfortunately I can't find the release date of the sequel, but just as soon as I do it's going on my calendar.
