Little Red Gem — D.L. Richardson

Ruby Parker isn't a witch, she's a singer in an all-girl band. But when she dies in a car crash, she becomes desperate to return from the afterlife to be with her boyfriend, Leo Culver, and uses magic to do so. Everyone except Ruby knows that magic comes at a price. She makes a mess of things and when the chance comes to undo the past, she's not sure how far back she should go to save young love.
