The Catastrophic History of You and Me by Jess Rothenberg
Published 2012 Razorbill
This wasn't as catastrophic as I thought it would be.
In the first few pages of this YA novel we discover main character Brie has died of a broken heart. Yes....really.
It happened just after her boyfriend Jacob told her he no longer loved her and now she is stuck in some sort of Pizza Palace limbo with a swoonable 1980s guy named Patrick, trying to explain that there's been a terrible mistake and that she needs to go back - that she's not really dead at all.
Except she is. Patrick keeps her company as she moves through the five stages of grief.
Its teen fluff, could've been worse though it did lose me a little towards the end.
