Angel’s Smoke by Aimee Robinson

Find his soul’s spark. Make it back home. Only problem? His soul bond is pregnant with another man’s child.
For untold eons, Iron has been the dark horse of the fallen angel sentinels, with a haunted past that plagues his future. Others keep a wide berth while he keeps his eyes on the prize: returning to the Empyrean after falling to the mortal realm. But when heated dreams finally show him his ticket home, the mate they reveal is single, pregnant, and prefers solitude to the support she very much needs.
Regret has chased Anna Malone so far up a mountain that the view has become more enticing than reality. The only thing worse than a life in shambles is the rugged mountain man who keeps popping up in her dreams as well as traffic jams. She’d be terrified of him if he didn’t also save her during the worst late winter storm to hit their small town in years.
But Anna will soon find out there’s more to the man than she bargained for and not just the way he sets her skin to scorching. Demons are real, and they’re about to play their trump card. If Iron and Anna don’t play along, their hard-fought happily ever after might just go up in smoke.
