“To think of death as a thing of beauty: that’s a threshold you can’t cross twice.” The truth is out, and Emmy is faced with a choice she dreads: surrender her mortality, or allow her frailty to threaten the nascent society the Silver are building. With exile the only reasonable alternative, she struggles with feelings she can’t define and a duty she’s reluctant to accept. While the Silver city hangs in the balance, Emmy must remake herself to redeem it and save her friends. Her reinvention forces her to choose sides, threaten alliances and risk becoming like those she fears: inhuman. The Silver Bullet is the final book in Josie Jaffrey's Solis Invicti paranormal romance quadrilogy, set in a dystopian, post-apocalyptic London where a deadly infection threatens to wipe out humanity. The only people who can stem its advance are the Silver, a vampiric race who offer a simple exchange: protection in return for blood and subservience.
