Science Fiction Alternate Universe

This world is trying to kill Lily Proctor. Her life-threatening allergies keep her from enjoying experiences that others in her hometown of Salem take for granted, which is why she is determined to enjoy her first high school party with her best friend and longtime crush, Tristan. But after a humiliating incident in front of half her graduating class, Lily wishes she could just disappear. Suddenly, Lily is in a different Salem - one overrun with horrifying creatures and ruled by powerful women called Crucibles.

Miriam Beckstein is a young, hip, business journalist in Boston. She discovered in The Family Trade and The Hidden Family that her family came from an alternate reality, that she was very well-connected, and that her family was too much like the mafia for comfort. She found herself caught in a family trap in The Clan Corporate and betrothed to a brain-damaged prince, and then all hell broke loose. Now, in The Merchants' War, Miriam has escaped to yet another world and remains in hiding from both the Clan and their opponents.

Sixteen-year-old Winnie Schulde has always seen splits - the moment when two possible outcomes diverge, one in her universe and one in another. Multiverse theory, Winnie knows, is all too real, though she has never been anything but an observer of its implications - a secret she keeps hidden from just about everyone. But her physicist father, wrapped up in his research and made cruel by his grief after the loss of Winnie’s mother, believes that if he pushes her hard enough, she can choose one split over another and maybe, just maybe, change their future and their past.
