I love her Paladin books, which explore a lot of variations on the general theme of “what happens to a good person with an all consuming higher calling when the source of their faith goes away.” And also has a lot of random weirdness like ninja accountants and giant clockwork mechs. They’re all romantic fantasies in the truest sense, in that there’s both a fantasy quest plot and a romance plot, bit of which are essential to the overall book and get equal attention.

If that sounds appealing, the one to start with is Clockwork Boys, which is a duology that concludes in The Wonder Engine. She then spun that off into the Saint of Steel series (but I think Clockwork Boys makes a better entry point as it sets up the general worldbuilding in more detail).
