Leo Dooley is a only child. Right? That doesn't seem to be the case when Lycoris, - his sister! - shows up, with her brother, and proves to be a Child of the god of Death. Not only that, but a new threat has arisen, and only Leo and Lycoris can fight it. Now a family torn apart must travel across the world to save the Gods, not to mention every halfblood alive, as well as the human race as collateral. Are you ready? They sure aren't.
