A love story by Rainbow Rowell, the New York Times bestselling author of Eleanor & Park. Cath and Wren are identical twins, and until recently they did absolutely everything together. Now they're off to university and Wren's decided she doesn't want to be one half of a pair any more - she wants to dance, meet boys, go to parties and let loose. It's not so easy for Cath. She's horribly shy and has always buried herself in the fan fiction she writes, where she always knows exactly what to say and can write a romance far more intense than anything she's experienced in real life.
