"Crossed" (Book 2 in the Matched trilogy) by Ally Condie. Seventeen-year-old Cassia sacrifices everything and heads to the Outer Provinces in search of Ky, where she is confronted with shocking revelations about Society and the promise of rebellion.
Orphaned Mary seeks knowledge of life, love, and especially what lies beyond her walled village and the surrounding forest, where dwell the Unconsecrated, aggressive flesh-eating people who were once dead.
Reached by Ally Condie- last book in the trilogy Matched. By far one of the best set of books I have ever read. So good that I'll probably re-read them haha. Everything just comes together perfectly in this last book. A must read!
