The world is ready to be reborn... Protected by the Church for four hundred years, the people of the City are the last of humanity--or so they thought. Echo Hunter 367, made to be faithful to the Church and its Saint at all costs, embarks on what she's sure is a suicide mission into the harsh desert beyond the City. Then, at the end of all hope, she stumbles on a miracle: another enclave of survivors, a lush, peaceful sanctuary completely opposite of anything Echo has ever known. But the Preserve has dark secrets of its own, and uncovering them may cost Echo more than just her life. She fears her discoveries will trigger a final, disastrous war. But if Echo can stop the Church and Preservers from destroying each other, she might have a chance to achieve her most impossible dream--saving the woman she loves.    "Echo Hunter 367 may be a clone and callous killer, but she's one with true heart and soul. Regeneration is a thrilling conclusion to Berg's dystopia duology."    -- Beth Cato, author of The Clockwork Dagger series "Regeneration by Stacey Berg is a paean to resistance, hope, and love, a Canticle for Leibowitz that passes the Bechdel Test and then some. This post-apocalyptic clash of values and technology demonstrates beautifully that physical bravery can only take you so far; real change only happens when we have the courage to listen."    -- Nicola Griffith, author of Hild
