Elenna Dashkov never even considered the idea that there might be other realms. She was a normal girl: wasn't suffering from prophetic nightmares, wasn't having flashbacks of a previous life, wasn't being stalked by creatures of the night. All in all, the was no sign that she was ever going to be dragged into the world of the supernatural, not like in the books. So how did she end up slowly falling in love with Death himself and hiding from monsters that wanted her, dead or alive? The answer is simple: association. When a mysterious guy who calls himself 'Guardian' shows up and there is obvious bad blood between him and her best friend, Helle, unexplainable things start to happen. People end up dead, shadows move of their own accord and monsters stalk the darkness. When Elenna ends up in The Underworld 'for her safety' she realizes that there is much more to Helle than she'd ever imagined and that if she wants to survive in the Realm of the Dead, she must decide whether she is to be the protector or the protected.
