Reading is a very subjective experience. What I may like may be completely different from what someone else likes.
An explanation of my categories is necessary. These are my very own made-up categories, and as such, they reflect my mood for a particular type of read. We each have our own, so if you don't see one of your moods here, please let me know!
Romantic Comedy -- a contemporary that'll make me laugh.There may be some elements of mystery or suspense, but this book doesn't have me looking under the bed. My personal faves are Jennifer Crusie and Susan Elizabeth Phillips.
Contemporary Relationships -- these books focus on the relationship and tend to be more emotional. I pick one of these up when I want to get into the characters. My personal faves are Kathleen Gilles Seidel and Deborah Smith.
Romantic Suspense -- these are the ones that keep you up at night. Serial killers, murderous family members. These take me on a fast-paced ride on the dark side. My personal faves are Lisa Gardner and Linda Howard.
Light Historical -- these are pure froth. Most I can't even remember the second I've finished them, but they are thoroughly entertaining and keep me flipping the pages. Light on history, heavy on banter. My personal faves are Julia Quinn and Eloisa James.
Heavy Historical -- the opposite of light. Not necessarily heavy on history as much as heavy on story or suspense. The characters are more fleshed out and may be darker than the romps. My personal faves are Laura Kinsale and Meredith Duran.
Historical America -- I personally prefer European historicals, but some authors are so good, you'll read just about any book they write. A couple of authors who fall into this category for me are Catherine Anderson and Jodi Thomas
Historical Georgian -- these are very similar to regencies, but the time period is different. The Scottish Uprising and the American Revolution figure prominently in the story. My personal favorites are Jo Beverley and Patricia Veryan.
Time-Travel -- another category I don't read much of. I guess I get too caught up in what the realities of such a situation would actually be. I do recommend Diana Gabaldon and Constance O'Day-Flannery.
