As far as series available in KU, I just finished the first three books in the Kings of Avalier fantasy romance series by Leia Stone, in a bit of a binge-read over the weekend, and am about to start the fourth and final one, which just came out a couple of days ago. (Not by my planning, but by happy coincidence...)
They are a little bit trope-ish, but with some interesting tweaks here and there. And some nice world-building. And just kind of fun, IMO. Oh, and I tend to skip pretty fast over some of the steamy stuff in romance novels, if there is a lot of it, and I didn't end up skipping too much on these.
