Angelborn. The Eternal Flame Series, #1

He gave up eternity for love. and lost. Now he's back for a second chance. Caleb is a half-angel with a one mission: find his reincarnated soulmate, Genna, and convince her to share her soul with him before dangerous angels drag him back to purgatory forever. It should be simple, but there's a complication he never saw coming: Genna's roommate, Maia. Cynical and guarded, Maia sees ghosts-and she's sure the handsome, mysterious man haunting her roommate is just another spirit to ignore.
But as the truth of Caleb's identity and the danger hunting him is revealed, Maia finds her hardened shell cracking. She's a distraction Caleb can't afford, yet she's the only one who sees the real him. And as celestial forces close in, she might just be the one worth dying for. Again.
