Going through an attic is like a treasure hunt, especially when you're going through someone else's. Like Forrest Gump said, you never know what you're gonna get. Leah Coombes thought she knew exactly what she was in for when she started to sort through her mother's attic, but what she didn't expect to find was an old box filled with letters addressed to a missing girl called Hope. With the help of the letters and added research, Leah discovers that Hope disappeared during a stay at Sunnyside Recuperation Camp for young mental disorder sufferers, but through the eyes of Myka, Hope's sister, she witnesses a new found love, a break in and a type of desperation she didn't realise existed. Armed with Myka's letter, Leah vows to find out exactly what happened to Hope during that month at Sunnyside, but with the camp and other witnesses proving impossible, can the truth really be uncovered?
