As an author of universe hopping stories I really enjoyed this opening act to this trilogy. As I was finishing reading this book one line came to mind Jane the universe hopper which is accurate. Jane starts off as a physics student before being pulled into another universe by her nemesis. Through out the book Jane jumps from one universe to another with the use of a multiverser which she was working on at the beginning of the book and soon she becomes a member of an underground Federation that helps to restore the universes after her nemesis creates an order to control them. Needless to say I'm looking forward to reading the second and third books in this trilogy. On another note this trilogy would make for a great set of films.
