Door to alternity - Nancy Holder and Jeff Mariotte

In Los Angeles, Angel and Buffy compare notes and realise that both are dealing with cases of missing teenagers, most of them children of rich and powerful parents. Coincidence? Or is there something more sinister at work?
Then Buffy learns from Giles that all hell's let loose in Sunnydale. Back on her home turf, she finds the doorway through which dark forces are gaining access to our universe. Renegade scientists have discovered how to open the portals between realities - could this explain where the missing kids are hidden? But opening dimensional portals near a hellmouth is a tricky business: you never know who or what you are going to attract. With the lives of the kidnapped teenagers - and one dangerously talented young woman - at stake, Buffy and Angel join forces to do battle in the uncharted dimension...
DOOR TO ALTERNITY is the middle volume of a stunning new crossover series which begins with Unseen 1: THE BURNING in June 2001 and concludes with the final part of the trilogy, Unseen 3: THE LONG WAY HOME in October.
