The Angel chronicles. Vol. 3 - Nancy Holder

'She's stronger than any Slayer you've faced. Force won't get it done. To kill this girl...you have to love her.'
For Buffy, birthdays aren't all parties and cake. Hers tend to involve a life-and-death battle with evil. And her seventeenth is no exception, when vampires Spike and Drusilla plan their own surprise party for the Slayer, with a deadly and apparently invincible demon as the grand finale. Then, a brief moment of happiness in the course of single night of passion with Angel changes everything. Suddenly, Buffy must deal with not one but two manifestations of evil: the almost indestructible Judge - and the legendary vampire Angelus, who is determined to exact his own special brand of revenge on the woman who showed him true love.
