Buffy The Vampire Slayer and Angel Books

ANGEL VS. SPIKE Sulking around the Slayer in Sunnydale, the vampire Spike has often run into demons intent on punishing him for throwing in with the White Hats. But when there are hints of a more organized campaign dedicated to vanquishing the vampire with a chip in his head, Spike sets off on the trail of whoever's put a hit out on him. Meanwhile, in the City of Angels, the vampire with a soul finds that the search for a mystical object is tied to his days as the vicious Angelus. Then Spike -- his former partner in carnage -- arrives in L.A. Each nursing a grudge, and with the specter of Buffy in both of their (cold, dead) hearts, the two vampires reluctantly work together...until their torturous past catches up with them!

"You never know until you're tested." -- Doyle, "Hero" Since he arrived in Los Angeles, Angel's mission has been to help the helpless. He has saved countless innocents in his city. However, one escaped his grasp: Doyle, the half-demon who came to Angel on a vision quest. Doyle sacrificed himself and in turn reconciled his internal conflict toward his own demonic heritage, leaving Angel and Cordelia to carry on with the good fight. And fight they do. But as the group squares off against evil in the City of Angels, little do they know that back in Sunnydale, trouble is brewing. A shakedown of snitches yields info: Someone other than Buffy has been slaying -- and whoever it is, he or she is strictly after half-breeds, going so far as to lie in wait to attack. It doesn't add up, and the Scoobies are stumped. But back in L.A. the picture becomes clearer when Angel Investigations is visited by an unexpected guest....
