Hitomi Beaumann isn't supposed to live to see her 18th birthday.
Hitomi has always been just an average girl in a small town. But now she's being followed and her skin prickles every time the eyes are on her. After escaping a brutal attack thanks to a mysterious young man, she discovers he is one of the ones who have been watching her. Obsidian has jet black hair, red eyes and an attitude to match. As she finds herself drawn to Obsidian, she also realizes that he might just be as evil as he wants her to believe.
With someone trying to kill Hitomi and her birthday drawing closer, she finds herself plunged into a reality where a power struggle has been raging for years between mystical realms, humans are not the only beings and most of her life has been a lie.
Will Hitomi make it to her 18th birthday to discover secrets hidden from her? Will Obsidian be there to protect her or will he be the one to end her?
