Sequel to The Death God Alliance. Nico, Percy, Sadie, and Carter must work fast to prevent another inter-pantheon incident when mysterious deaths start occurring at Camp Half-Blood right after the Kanes are accidentally picked up in a demigod extraction.

"Sorry," said the son of Hades, "but if I surrendered to an organization called the House of Life, my dad would kill me." After a run in with the Kanes, Nico unwittingly ends up becoming a host for the Egyptian death god Anubis.
