Molly wants nothing else but her family back together and happy again. She could care less about the Syndicate.

But when clues surface to their whereabouts, Molly can't resist taking on a new adventure. In the final showdown with the Syndicate, she must resist the urges of betrayal, wrath, and deceit to come out victorious and rid them from her life forever.
