The many changes the Cubi people have seen since their King rose to battle a hidden war are not over. The newly risen King must go abroad to assist Nol-Elakdon in his Kingdom of the North as the changes have reached other Kingdoms.

That leaves Aaron without his childhood friend and the support system he needs as he settles with the new knowledge of himself as a Halfling to rise an Incubus. Aaron doesn't do well with being abandoned. To secure him, the King makes sure that Aaron's Incubus father rotates home to get to know his son.

Lord Matadon has finally learned of the child he'd been sent into the human world to father, yet he knows it'll be a challenge for them both to establish a father/son relationship. He quickly learns that they share a common passion, which can hopefully bind them closer together.

That shared passion and fragile relationship is put to the test when the Grand Council deems Aaron and Matadon the two most likely to succeed in a mission where they're to assist trained hunters and Guards in tracking down missing Halflings in the human world.
