Angel & Faith

"When Angel was broken, alone, and in need of a friend, Faith took charge and restored him to health. When he set his sights on righting one of his many wrongs--by resurrecting mentor and Watcher Rupert Giles--Angel again needed her help. Now Angel's quest has come to the final stage, but not without great cost to Faith... And not without interruption: Big Bads Whistler, Pearl, and Nash have entered the last phase of their ultimate plan to unleash a magical virus that could kill billions while forcing the evolution of life on earth."--Back cover.
