This book was an emotional roller coaster ride for me. I've been reading about Sasha since her debut in "Slack". Even though she is a side character in Ford/Ashleigh, James/Harper and Merc/Sydney's books, she came off as strong as the main character. I highly recommend you start at the beginning and get to know everyone before you read Sasha's story. It made this book that much sweeter. This book broke my heart and mended it back with jagged little lines. All I want to do now is go back and re-read every single one over again and you will too!
