Recently, I've loved
ZA Maxfield (also available
with periods after the initials) and
LA Witt; they're both on the "just buy everything as soon as I can afford it" list. Both write M/M erotica; I gather that LA Witt writes het romance as well under a different name, and I want to track down some of that. I believe they also have other works that don't sell through Fictionwise, but I like multiformat options; not yet up to buying from the mess that is AllRomanceEbooks.
I've also loved the PsyCop books by
Jordan Castillo Price; psychic cop investigations with a gay protagonist.
