Books that isn't available:
All Stieg Trenter's novels ( I think they will be this time next year, though.)
Devon Monk's Allie Beckstrom novels ( swallowed up in the shift to agency pricing)
Sweet Temptation by Maya Banks ( swallowed up in the shift to agency pricing. I think)
Oh. JA Konrath's Jack Daniels novels. The latest is but not the previous ones. sigh. ( I'll get his other stuff from Smashwords while I wait)
There are probably a bunch more that I am forgetting
