Peter Grant, series sub world of magic in london

An old one that you might enjoy...........WeaveWorld by Clive Barker. The basic premise is a world inside of a carpet...but a very magical world it is.

Jim Butcher's Dresden Files are pretty good.

Christine Amsden's Cassie Scot series. It has some romantic elements, like, I think, the series you mention in your OP.

Thieves' World shared series created Robert Asprin.

The Magicians by Lev Grossman has an intesting word. I think they have a TV series right about now.

Elizabeth Hunter The Elementals series

The Land of Stories series by Chris Colfer (aka Kurt Hummel from Glee)

Anne Bishop - Dark Jewels/Family of the Blood series

[Dendra]

The Kate Daniels series by Ilona Andrews. Set in and around Atlanta, GA after magic waves have started flooding the world, roughly 50 years in the future.
