Eden Summer, Paperback/Liz Flanagan

Shy, gothy Jess and stunning and popular Eden are best friends. They've supported each other through some of the hardest things you can go through - death, bullying, love, heartbreak. They know everything about each other. But then Eden goes missing and Jess knows she has to find her, and fast, because the longer someone is missing, the more likely it is they won't be found. So Jess starts exploring her memories, things Eden said and did in the last few months and she starts to realise that maybe they don't know each other as well as she thought.
