Parallelogram

Audie Masters is a 17-year-old girl who doesn't have it all: not a lot of money, not much confidence around guys, she can't seem to pass algebra, and she's desperate to get into the college she's been dreaming of for years. But what Audie does have is a knack for physics that's about to catapult her into the adventure of a lifetime. Now all she has to do is survive it.

In a desperate move to save the life of her parallel self, high school science genius Audie Masters managed to bend the laws of physics. But now she's trapped in the wrong universe, with no sign that her scheme to save her alternate self, the famous teenage explorer and adventurer Halli Markham, actually worked. Until she can sort out the physics of what went wrong, Audie has to pretend to be Halli - and fool everyone from Halli's parents to the guy who's in love with her.
