Had Me at Halo

A man travels back in time to reclaim a lost love, but develops forbidden feelings for his guardian angel along the way.
When Liam Evans dies, he loses the woman of his dreams, Sienna. But thanks to his guardian angel-Amara, he gets the opportunity to relive his life to prove him and Sienna belong together.
But as Liam tries to win over Sienna, he discovers that she may not be the best fit after all. Meanwhile, Amara and he connect. Really connect. Unfortunately, there's a time limit and he's just starting to understand his feelings. If he makes the wrong choice, it'll cost him happily ever after.
Amara Farouq is a guardian angel who hates the Afterlife. Angels offer criticism like it's small talk and Amara is exhausted from keeping up with impossible expectations.
Then she meets Liam. He's thoughtful, handsome, and annoyingly charming. Through him, she finally finds the safe space she's always wanted. Amara falls in love, despite it being forbidden. She knows she can never be with Liam, but when he offers a level of intimacy she's been denied for so long, it's going to take every ounce of her willpower to let him go.
