Miserere by Teresa Frohock (17)
I picked this up on a whim. I heard it was good, but got bad marketing because the publisher ran out of money and collapsed. I liked it. It's pretty short (under 300 pages), has decent writing, good characters, some intense moments. The setting is kind of a barrier world between hell and earth, with the main characters as the force preventing the fallen/demons from conquering earth and being able to war against heaven. In this place are supposedly all religions working together, but aside from brief blurbs, the characters are all christian-centric. Which isn't bad, but I would have liked a more diverse cast, or at least some more detail of the other groups' roles in the world. As it is, I enjoyed the interesting take on these religious mages using psalms and prayers to channel power, etc.
Reading some author comments online after reading, she said one big problem with the marketing of the book was that they decided to sell it in christian book stores. I certainly don't blame whoever was in charge for making that mistake, but it surely would have bothered any wholesome parents trying to shelter their kids from secular fiction. (There's swears, violence, gore, sex, abuse, oh my!) So I'm not sure the audience for this one, it has enough overt christian religiosity to scare away the non-religious, but is plenty gritty to stand alongside others in the "grimdark" genre.
I'll probably check out some other stuff by Frohock at some point. She has other unrelated fantasy. While the ending was satisfying, this book could easily have sequels, but it seems unlikely after 10 years.
