The never list
(Book)

"A novel"--Jacket.

"For years, best friends Sarah and Jennifer kept what they called the 'Never List': a list of actions to be avoided, for safety's sake, at all costs. But one night, against their best instincts, they accept a cab ride with grave, everlasting consequences. For the next three years, they are held captive with two other girls in a dungeon-like cellar by a connoisseur of sadism. Ten years later, at thirty-one, Sarah is still struggling to resume a normal life, living as a virtual recluse under a new name, unable to come to grips with the fact that Jennifer didn't make it out of that cellar"--,Provided by publisher.
