This is how you write a good angel book. 
 Scratch that. This is how you write an AMAZING book in general. 
 Angelfall has skyrocketed to the top of my favourite books list by having everything I could ask for in a book. 
 Penryn and Raffe were, by far, the stars of this novel. Oh boy, do I love these two. They're both extremely well developed, by themselves and as a pair. Penryn is one of the most badass heroines I've ever come across in a book, willing to do whatever it takes to rescue her sister. She's been forced to grow up fast in a world that's been destroyed but there are moments when she still comes across as a lost and confused teenager. Raffe is a combination of witty, compassionate, gorgeous, and broken. His past before meeting up with Penryn is still mostly unknown, and I'm dying to know more about it. 
 This story is the perfect combination of dark and gritty mixed with perfect spots of comedic dialogue and a slow-burning relationship between the two MCs that never takes away from the action-packed plot. 
 On a final note, kudos to the author for expertly integrating angel folklore into the story. It gives it an authenticity that you rarely find in such novels. 
 This book is a must-read for everyone! Waiting for the sequel released in the fall of 2013 might just kill me.
