Carrier

From the day she was born, Lena has viewed the world through the jagged window of a razor-wired fence. The hundred-acre property she shares with her mother in the Australian outback may keep her safe from the Y-Carrier disease, but it is no longer enough to hold Lena's interest, and her mother's increasingly tight grip on her free will is stifling. Just as her curiosity blooms and her courage rises, she meets a boy through the fence - the first boy she has ever laid eyes on.
His name is Patrick and he comes with a dangerous yet irresistible invitation of adventure beyond the fence, an invitation to which Lena cannot say no. But Lena's newfound freedom is short-lived and she soon discovers that the Y-Carrier disease is not the only enemy she faces on the outside. Her new enemies want something Lena has, and they are willing to do anything to get it... Carrier is a YA novel about freedom, choice and family - and the terrifying disease that makes them mutually exclusive.
