Neither sister remembers being bitten by Renz, but both are overcome with a desire to consume blood, a desire they fulfill by feasting on small animals. The sisters attempt to find a cure for their condition, but will they be able to do so before Renz achieves his true goal of turning Destiny into a full vampire?
