Angel and Faith, Volume 3: Family Reunion — Christos Gage

Angel's quest to resurrect Giles from the dead has brought an old friend to London - Willow! Tensions run high as they confront the loss of Giles, but before blood can be shed, Willow has a proposition. She'll help Angel on his quest if he'll help her find magic. To do that, she'll need Connor, Angel's estranged son and the only one who can get them into Quor'toth, a fearsome hell dimension where magic runs deep. Good thing they'll have reliable ol' Faith to keep an eye on their progress and motives...
