But fighting Ticks comes at a terrible cost to twin sisters Mel and Lily and their best friend Carter. With Lily exposed to the Tick virus and lying in a coma, it''s up to Mel and Carter to search for the cure - and quickly. For with every passing heartbeat, Mel is becoming more and more purely vampire. Now their only choice is to split up in a race to save Lily - and to save humanity.
