Apricity by Miley Green

Hannah Walker is done living up to impossible standards.

She’s traded perfectionism for stripper heels and a heart of ice. She doesn’t need a hero—and she definitely doesn’t need a man.
Sarge has traded one uniform for another.
A combat veteran-turned President of the Saints of Hell, Sarge lives in the gray area of the law. He’s used to life on the road and the solitude of being a bachelor, but Hannah gets under his skin.
Unfortunately, with Sarge doing the right thing the wrong way, it puts a target on Hannah’s back. After a rival club takes his Butterfly, his world turns blood red with vengeance. While Sarge tears through a web of betrayal to find Hannah, she fights to keep her spirit from breaking in the dark.

Can they find warmth in each other during the coldest season of their lives?
