Out in the Cold (In From the Cold #4)
Lee Brazil

But Finn seems a little cold…a little distant, and a lot more eager for his departure than Cannon expected. Could there be something Prince Finn needs that Cannon isn't giving him?
Finn Lorensson is torn…while he'd like nothing better than to crawl in bed with Cannon and never come out, he's got real world villains to deal with, and Cannon is a lot safer in Atlanta. So he steels his resolve, and pushes Cannon away, feeling the pain of a broken heart is the just reward for his perceived misdeeds.
Sometimes, even the kiss of a frog prince isn't enough to repair a rusty suit of armor.
