Labyrinth to Tartarus by C J Carella

Hawke Lightseeker has rescued his fellow Eternals, but his problems are just beginning. An Undead-Fae aberration threatens the lands to the north, and Hawke must deal with it by leading his friends into a deadly Dungeon. And if it wasn't enough, Hawke has assassins infiltrating his Domain, a pair of baby monsters he has adopted, and gods and Arbiters watching over him, ready to crush him if he gets out of line.
