What Happened To Goodbye (Sarah Dessen)

Mclean never lets herself get too attached... After the scandal of her mother's affair, Mclean and her dad chose life on the road. But since losing her family and home Mclean has lost herself too; she's been Eliza, then Lizbet, then Beth - changing her name as often as she changed towns. Her neighbour, Dave, is like no one she's met before.
