Of the same kinds, class, or nature

I need recs! I'm going to Florida for a week, in two weeks, and I need books. A few things:

(1) It needs to be in paperback (I get hardcovers from the library and that usually takes a while)
(2) I like historical romance fluff
(3) Thinky things make my brain hurt
(4) Well done contemporary romance is good too

I have read everything by:
Eloisa James
Julia Quinn
Stephanie Laurens
Mary Balogh
Julie Garwood
Judith McNaught
Amanda Quick/Jayne Ann Krentz/Jayne Castle
Linda Howard
Elizabeth Lowell
Susan Elizabeth Phillips
Liz Caryle
Debbie Maccomber
Diana Palmer
Donna Andrews
Julia London
ETA: Georgette Heyer - I've read almost all of them!

I no longer care for:
Nora Roberts
Catherine Coulter
Jude Deveraux
Iris Johansen
Lisa Kleypas

I have tried and didn't really care for:
Sabrina Jeffries
Celeste somebody
