Books in the Death-Cursed Wizard series

The idiot gods are being murdered. An unexplained malevolence severs them from the world of mankind and reduces them to feckless insanity, and they weren't all that stable to start with. Now one of the gods' most horrendous enemies slaughters them while they hide in different realities, much like divine, lunatic bunnies. The Blacksmith of the Gods, Fingit, has been mocked by his fellow gods since the beginning of time, but now only he is still lucid enough to conceive a scheme to save them and maybe reality itself. Fingit contrives a plan so clever that if anyone dies it won't be him. But the most deranged being in the universe, his sister Sakaj, drags him into her own lunatic scheme. Fingit must outwit her, defeat the gods' foes, overcome the entity that is thrusting them into oblivion, and grapple with the most singular problem of all-while the gods have been gone, has mankind cared? Or even noticed?

Cursed to take lives for the God of Death. Sorcerers must give up things and people they love, or accept things they despise, to gain magical power. The sorcerer Bib saves his daughter by accepting a curse to murder people, and only Death knows how many Bib must kill. He tries to slay only evil people, but soon finds he's also killing people who are merely bad, or who might someday become bad. Bib chases a brutal sorcerer to help a woman rescue her boy, mainly because he expects a lot of killing. But he doesn't expect to unearth obscure magic, enslave spiteful supernatural beings, and strike ghastly bargains with the childish gods. And the last thing he expects is to face the question-is he a good man cursed to crave murder, or has he always been a murderer at heart?
