Rakish by KT Yarrow

He wanted to take a stand. But he didn’t have to stand alone.

Julian Heroux doesn’t want to be a paladin anymore. The guild used to be a force for good, but now they’re turning on their own members and hunting down those who disagree with them. To take a stand and free himself from the rising tyranny within the ranks, he turns in his guild ring and quits. But they won’t let him go without retribution.
Valac hasn’t touched mortal soil in centuries. When duty finally calls him back, his mission is simple: find out what happened to Lilith, and choose a suitable candidate to replace her. The last thing he expects is to be captivated by a stubborn former paladin with an unbreakable moral compass. Julian is the first human who’s never treated him like a monster. He should focus on his mission, but Julian Heroux proves to be an irresistible distraction.

Valac recognizes something in Julian, and he won’t let the guild destroy it. He’ll have to make new alliances to protect what’s his, and Julian will have to reckon with enemies that he once thought of as family.
