According to amazon.co.uk, the UK edition of Kiss of Life by Daniel Waters isn't out until 6 July but I spotted it today in Waterstone's.
Kiss of Life is the sequel to Generation Dead.
The UK cover is on the left, the US edition, which was published in May is on the right.
Synopsis: The phenomenon that's been sweeping the country seems to be here to stay. Not only are the teenagers who have come back from their graves still here, but newlydeads are being unearthed all the time. While scientists look for answers and politicians take their stands, the undead population of Oakville have banded together in a group they're calling the Sons of Romero, hoping to find solidarity in segregation.
Phoebe Kendall may be alive, but she feels just as lost and alone as her dead friends. Just when she reconciled herself to having feelings for a zombie -- her Homecoming date Tommy Williams -- her friend Adam is murdered taking a bullet that was meant for her. Things get even more confusing when Adam comes back from the grave. Now she has romantic interest in two dead boys; one who saved her life, and one she can't seem to live without.
