Hi Immery!
ML's Nowhere To Run fits your specs perfectly. It's got a few darker places, but it's got lots of LnC interactions, which ML always handles with a special kind of 'make you grin'.
Treasure Chest by Female Hawk, a classic LnC romance, I'd say.
And then there's Written in the Stars by Beth Summerson, another one with LnC getting together in special circumstances.
Hope that helps
Michael
