Molly Molloy and the Angel of Death by Maria Vale

From Sungrazer Publishing:

"A weird, adorable stunner of a romance." -- The New York Times

Death needs a do-over.

Azrael--Grim Reaper, Destroyer, Angel of Death--has messed up. Instead of taking Molly Molloy's soul, he accidentally saves her from choking on a chicken wing.

Molly has been visited by Death before. He took her parents, her grandparents. Her first love.

But now this utterly unexceptional waitress at a breastaurant in New York can see him. Touch him. Talk to him. Say 'no' to him. Make him doubt.

The Powers that Be are waiting for Death to fix his mistake but before he can, he makes one more...

He falls in love.
