Plot synopsis: In an isolated small town in the Pacific Northwest, Sylvia's teenaged life of juggling two boyfriends and an overprotective father is turned upside down when she discovers she has a bizarre virus which has randomly plagued the women in her community for decades and shamefully forced those afflicted into hiding. Sylvia undergoes a horrifying physical transformation, and she finds herself drawn into a persecuted underworld where she begins an astonishing journey of freakish self-discovery. Marker is a classic coming-of-age tale with a horror twist, which pits its heroine against her oppressors - the town's non-afflicted - in a battle for self-determination--and survival.
