Mojo Queen and Red House are both about paranormal investigator Roxanne Mathis, who just so happens to be a practicing witch. Often aided and abetted by her ancestor, vampire Daniel, Roxie spends Mojo Queen doing battle with a demon summoned into a young woman, while in Red House, she's fighting to clear a B&B of malevolent spirits. In both books, she's both frustrated and tempted by Blake the Sexy Sorceror, a devillish young man with a penchant for chaos magic.
I don't normally read paranormal romance but these books are closer to urban fantasy, and there's enough of the cool energy-blasting and ghost busting to make me rather keen for the next instalment, Hoodoo Woman. Roxie is a strong and independent heroine, with a taste for the blues and a capable streak that made me warm to her pretty much instantaneously, and Daniel is one of the coolest vampires I've come across in a very long time (he's in the same league as my beloved Xan Marcelles). Even though Blake is by turns an arrogant so-and-so and a dangerous man, he's also Very Sexy and the type of hero someone as strong as Roxie needs. He doesn't save the day, just lends a hand when she needs it.
I met Sonya on Twitter, and after reading some of her Friday flashes on her blog, thought I'd give Mojo Queen a go. I read it in a matter of days and treated myself to Red House just after Christmas, a book I read in about four sittings. Sonya writes in such a way that it's nigh-on impossible to put her books down, and her world-building is incredible - it feels both painfully real, and delightfully otherworldly at the same time. Roxie has a clear, straightforward narrative voice, and she's very easy to root for. The combination of the supernatural and other cultures makes for interesting reading, and I keep wanting to look up all of these other forms of practice for extra reading.
I can't actually recommend them enough, so it's fairly obvious they get a 5 out of 5 blunt pencils!
