Worlds Enough...and Time

Whenever things get rough, Roxanne escapes to other worlds. She possesses a talent that skips generations, a talent that no one else believes exists. Except her granddaughter Marissa, who exhibits the same talent. Marissa, who can open windows to other worlds with the movement of a finger. Roxanne wants to train Marissa to live with her talent, but the rest of the family wants to stop her. They fear Marissa will end up like Roxanne: difficult, unreachable, distant.
Worse, they fear Marissa will not survive Roxanne's training-or her love."Kristine Kathryn Rusch may be one of the most sure-footed authors in science fiction, never straying from the path of good story-telling as she dissects her characters and their situations for the reader's benefit."-Science Fiction Weekly
