Love story, sci-fi, action and irony about the prejudices with which we treat others are all there in this funny, funny and well-crafted novel about the future.  Only she can save the world.    Eighteen-year-old Jarrah is having a hard time. For her participation in a risky operation to rescue the military, she received the highest of humanity's awards and found herself - along with her disability - in the center of everyone's attention. Jarrah is one of the few unlucky enough to be born with an immune system that does not allow her to survive on other planets. And even though extraterrestrials call her a “monkey” and a “geek,” Jarrah intends to prove that girls from planet Earth are no worse than the rest.    But her beloved planet is in danger from what may be the first meeting with intelligent aliens in human history. Thanks to his knowledge and courage, Jarrah is back in the thick of things, but do other worlds need Earth enough to fight to save it?
