Kiss of Life by Daniel Waters is the second book in the Generation Dead books.
The rather strange phenomenom that is sweeping the country seems set to stay. Teenager's are still dying.....then coming back! Not only are the teenagers that have come from the grave still here, there are new ones raising from the dead all the time. Scientists look for answers, and politics make a stand as they do. Oakville's returning dead have banded together to form a group called the Sons of Romero.
Phoebe Kendall may still be alive but she feels as isolated and lost as the "living dead". Just when she has come to terms with her feelings for Tommy her homecoming date someone shoots a bullet at her...and her friend Adam protects her but ends up dead....then he returns. Adam is now one of the living dead. Phoebe finds herself romantically torn between the two undead boys, one who saved her life....and the one she can't seem to live without.
This was a good second book though it did have some slow patches in it, though it is certainly worth persevering and reading it. I also have to add that I think the covers are gorgeous!
