I loved THIS ONE'S FOR YOU by Kate Sweeney. The characters of Cass and Syd are richly drawn with distinct voices and well-developed back stories that make an impact on them in their day-to-day lives. I could not put the book down because I wanted to know where the characters were going (physically and emotionally) and how their actions would play out with their families. I intend to re-read it again because I raced through my first read!
