Holly-Anne Atkins is a normal 17 year old girl. There's nothing special about her. She has a great job doing what she loves, a great family, and a sister she actually gets along with. Nothing could've possibly touched her perfect world... Except for her sister's 23 year old boyfriend, Tristan. She falls head over heels for him in a heartbeat. She knows that it's wrong, but she can't seem to help herself. Will she be able to keep her perfect world together and keep her distance, or will everything come crashing down around her?
