Has anyone read "Villians by necessity"

[BiblioRook]

Hmm. Well, there was a definitive battle between Good and Evil where Good won and sealed Evil away forever. Years later the last of the druids came to realize that without Evil in the world the world was being thrown off Balance and could soon even destroy itself as a result and so took it upon herself to recruit the last few remnants of villainy she could find to go and reverse the seal Evil was put under. Meanwhile the last of the Legendary Heroes who helped seal Evil away in the first place seeks to stop them, not believing the whole 'the world will be destroyed due to a lack of Balance' nonsense.

Sorry if that was brief, it's been years since I've had the chance to reread this book. God do I really want to now.
