Her Dragon's No Angel
This one had the not-so-crazy about "fated mate" trope, but also a trope I generally do like- "forced proximity." Holly is a Christmas Angel with one more mission to complete before she can search for her soul mate. Problem is, she wasn't told what it was, only to go to this cave and wait. Tomas is returning from an errand and has to take shelter from a blizzard.
I liked both characters. Holly was in denial since she was certain her mate would be another angel (Tomas is a dragon). While there, they team up to rescue a magical being.
