When the vampire Dirk Calden visits the city of Moonlight Hills, he is in desperate need of help. He seeks the Shadow Assassins, a group of supernaturally gifted humans. They are asked to come back to his home land, the Second Realm, home of all ancient magic. The Shadow Assassins are ready for a job they think will be typical - cleaning up the messes vampires leave in the night, keeping the humans from finding out about vampire population that inhabits the city. Before they can start their job, they are attacked, separating the fiery half angel, half demon Evangeline from her friends - the shape shifter Kaleb, the earth mage Kaydee and the telekinetic Marco. Stranded in a strange, magic land, each of the Shadow Assassins will have to find each other, among the native populations of elves, werecats and faerie tricksters...as well as deal with a rising war and a king bent on eradicating the supernatural population from the land of magic they live in.
