The Wreck of Heaven — Holly Lisle

There are doors into other worlds -- and those who cross over are changed forever ...

Two women have discovered the way into a new reality -- one so close to Earth that events there have shattering repercussions here. On Oria -- a wondrous paradise and nightmare both -- Molly McColl has powers she never imagined ... and a destiny that threatens her life, her love, and her soul. While Lauren Dane must use an extraordinary, newfound magic to protect her young son -- and to join with her sister on a quest that will shake the foundations of Heaven itself. For a serpentine evil now threatens the worldchain -- a soulless, immortal enemy who feeds on the death of worlds, and who is now turning its hungry, malevolent gaze on Oria ... and Earth.
