Ooo, so many to choose from! I read a lot, too much sometimes, it has slowed granted with children...but I try not to let that deterr me, haha.
I have a huge list, I may repeat some suggested already
Anne Bishop, her Black Jewels Trilogy and other connecting books are always a favourite to go back and reread.
Jacquelyn Frank; anything by her is worth reading.
Nalini Singh; I just finished one of her recent releases from her Psy/Changling novels, always excellent as well as her Guild Hunter novels.
Kresley Cole: Immortals After Dark series
Anne McCathery, her Pern novels are classics to go back and read.
Larissa Ione, her demonica novels
Gena Showalter; love pretty much anything by her. Her Atlantis novels are good but I favour her Lords of the Underworld better.
Christine Feehan: you must read her books. MUST.
Sherrilyn Kenyon. MUST READ.
You can also find good reads by Laura Wright, Alexandra Ivy, Lara Aiden, and Donna Grant.
If you like to read something that is almost purely smut, Lora Leigh's Breed novels aren't bad.
David Clement Davies 'the Sight' and 'Fell' are worth a reread as well as any David Eddings books and Terry Brooks.
Ohh and Mercedes Lackey! I especially like her one series, beginning with Joust.
Lynn Flewelling's Tamir Trilogy is one of my old favourites.
Deborah Chester's 'The Sword, the Ring and the Chalise' trilogy is good as well as Alma Alexander's 'Hidden Queen' and 'Changer of Days'
If you don't mind dabbling into the teen novels to sweeter romances, Kelley Armstrong, Amanda Hocking, C.C. Hunter and Anthea Sharp have recently made it to my bookshelf and ereader. I have so many more books I could spit out but I better stop while I can, haha. I think I'll be going through my books now and getting a big stack to reread.
