I really enjoyed this book. It was so compelling. The characters were great, especially Sybil. And I loved all the different narration and voices which made it easy to know who was speaking.
At first it seemed like the book was just going to be a series of letters Sybil was writing, as well as the letters she received, but it pieced together into a great story and we got to know the characters by what and how they wrote. It was so enjoyable.
