Mythical by C.E. Martin
Returning to life with partial amnesia, Colonel Mark Kenslir eventually remembers his last mission: stop a shapeshifter on the loose in America. It can take the form, memories and even the powers of anyone- by ripping out and consuming their heart. Kenslir and his squad were sent to stop the shapeshifter, but were all killed by the monster.
Unarmed, with no support and not sure who to trust, Kenslir sets out with the teens to stop the shapeshifter’s killing spree.
