Tristan's Redemption by Candace Blackburn

David has everything going for him—a successful career and marriage to the love of his life—until one act of carelessness leads his death. Luckily for him, an angel gives him the opportunity for a second chance. The only catch is that Abby, his grieving widow, has to fall in love with him in his new body, before she gives birth to their son.

Abby's husband cheated on her, and died, all on the day she found out she was pregnant. Still in pain over her betrayal, Abby meets Tristan in a survivor's group and finds herself inexplicably attracted to this stranger. Despite questions over the similarities between Tristan and David, she can’t help falling in love. What Abby doesn't know is that she is the key, the only way Tristan will ever get over his own hurt and find his redemption.
