Fantasy novel about returning evil to the world

[Sarah]

Book starts out after some group has done this Great Quest and locked all the bits of EVIL god or something away from the world. The world is getting to be very boring.
The "Good Guys" are also trying to get rid of all evil by brainwashing people and destroying all races or creatures deemed evil.
So an assassin, a thief, an evil witch, a druid (she just wants balance too much of anything is bad), a Black Knight, and a bard all go questing to release Evil.
Maybe 20 years old, and the author might have been the child of another author?

Sarah, can you confirm that Aerulan and Tathariell's suggestion of Villains by Necessity by Eve Forward is your book?

"With the banishment of Evil from the realms, the final victory of Good is assured-unless a few stalwart antiheroes can save the world from a serious and potentially fatal imbalance... epic fantasy that features an assassin, a thief, an evil sorceress, a dark knight, and an implacable druid as the villains-turned-heroes who must restore the delicate balance of opposing forces before their world disappears in a blinding flash of Goodness and Light."

The author Eve Forward is the daughter of the late American physicist and popular science fiction author Robert L. Forward.
