IMAGINE THAT you could change your world with the flip of a switch. You might be prettier, more athletic, more popular, or even living on an exotic island, because your history - your world line - would be different. But here's the catch: you have no way of knowing if the reality on the other side of that switch will be better... or much worse. JACOBUS ROSE is a fifteen year-old who believes - as many fifteen year-olds do - that his life could use improvement. School is a numbing routine, and his parents' marriage seems to be imploding before his eyes. 'Maybe I was born into the wrong world, ' he thinks. Lured into a strange little house containing nothing but empty rooms and an oversized circuit breaker, he'll discover that reality comes in plural form, and that our choices create a continuous web of branching worlds, any of which is as 'real' as another. A solo odyssey becomes a duo, a trio, and then a quartet, as Jacobus befriends other interdimensional travelers along the way: GORDON NIGHTSHADE, the veteran pilgrim and chief theorist; MOSES DeWITT, the alley cat with an old soul; JEMMA DOONE, a girl of many-worlds who becomes the main river home for Jacobus and his crew; and finally, his lost friend CONNOR, who just may have preferred an alternate universe to his own. THE SWITCH is the story of their journey home. The question is: if they get there, will it be the same place they left behind?
