Haunt me / Liz Kessler.

Joe wakes up from a deep sleep to see his family leave in a removals van. Where they've gone, he has no idea. Erin moves house and instantly feels at home in her new room. Even if it appears she isn't the only one living in it. Bit by bit, Erin and Joe discover that they have somehow found a way across the ultimate divide - life and death. Bound by their backgrounds, a love of poetry and their growing feelings for each other, they are determined to find a way to be together. Joe's brother, Olly, never cared much for poetry. He was always too busy being king of the school - but that all changed when Joe died. And when an encounter in the school corridor brings him face to face with Erin, he realises how different things really are - including the kind of girl he falls for. Two brothers. Two choices. Will Erin's decision destroy her completely, or can she save herself before she is lost forever?
