Cassandra in reverse
(Book)

After an extraordinarily bad day during which Cassandra Dankworth's boyfriend breaks up with her and she is fired from her job, she wakes up the next day and has the chance to do it all again, differently.

Cassandra Penelope Dankworth is a creature of habit. She likes what she likes (museums, jumpsuits, her boyfriend, Will) and strongly dislikes what she doesn't (mess, change, her boss drinking out of her mug). Her life runs in a pleasing, predictable order...until now. She's just been dumped. She's just been fired. Her local cǎf has run out of banana muffins. Then, something truly unexpected happens: Cassie discovers she can go back and change the past. One small rewind at a time, Cassie attempts to fix the life she accidentally obliterated, but soon she'll discover she's trying to fix all the wrong things.
