I read all kinds of romance. I love regency but more contemporary romances are just as good in my opinion though I prefer the contemporary romances with a little murder mystery to them.
Maybe you know of this website already but I find HarperCollins has one of the best websites in terms of giving you chapter excerpts so you can decide beforehand whether to buy a new author or not.
Also I have given a link below which they frequently update books that you can read entire books for free. You can't download them unfortunately and they are only available I think for a month.
