Originally called The Infection, this is a pentalogy speculative post-apocalypse (zombie) mystery set in a futuristic setting.

Morning Light introduces 19-year-old Alex Carter, a determined college student who must escape the infested island she once called home. When zombies begin to mutate, she joins other survivors to find out who started the infection before the final evolution of zombies overtakes the island. Will they unravel the truth and escape or will they die trying? For readers who would be interested in the concept of what if a lone teenager joins (Alone by Megan E. Freeman) a diverse group of survivors (Teen Wolf) to survive on a zombie-infested island (Resident Evil by S.D. Perry).
