Reading the Wind - Brenda Cooper

The colony planet of Fremont was supposed to be free of all genetically

altered beings--a new home for a pure race.  So when six genetically altered children were abandoned on Fremont, they were not welcome.  They vowed to get off the planet by any means necessary.  Joseph  and the others managed to escape, although Joseph finds their new home hostile, frightening, and deeply challenging. Chelo is left behind with her new-found love, Liam, and her best friend, the troubled Kayleen. Both sets of teens must contend with hostile adults, daunting environments, and unexpected challenges. And when Chelo's very life is threatened, Joseph must find a way to save her.
