In Alatheia, nine planets exist much like ours in the Milky Way. Nathea is home to the Aketas who have lived peacefully as long as Nathea has existed, but a threat rears it's head. Queen Sybille lost her sister as a changeling over a century ago and she will do anything to get her back. Even if it means ending the world. Cimburleigh has no recollection of her previous life in Nathea, seeing as though she was taken away from there as a baby. But when her sister wants to bring her back there, Cimburleigh has to face something that she had rather not do. Kill the only person who cares about her. Callisto is haunted by his parents deaths and wishes to never end up like them - so in love that he would do anything, including die, for it.

But when he is informed that he must help save Nathea from destruction by Queen Sybille, he wasn't expecting to help Cimburleigh. Will he do the one thing he swore to himself that he would never do?.
