It's hard enough finding your place in high school. It's even harder when you have unexplainable, freaky moments of superhuman abilities. Ariel Sinclair is unfortunate enough to live this way, and things only get weirder once she meets Dimitri Valmont and his "family". Ariel soon learns about her biological parents, and how she is an Immortal-a Guardian of the human race. They ward off the supernatural creatures of fiction and myth, and defend humans selflessly. But is she willing to give up her semi-normal life just to be thrust into a complicated, extremely dangerous world she barely knows? Or will she turn her back on her biological responsibility and live out the rest of her life as ordinary as possible?
