By the Light of the Moon - Life's Second Chances, #4

A bitter heart is no match for a moonlit bridge, an enormous dog, and a determined optimist from Ogalalla.Mary Johnson has recently left her home in Nebraska after her husband of thirty years dumped her for a younger woman. She is walking her St. Bernard when she sees a man on the jumper's side of the railing on the Golden Gate Bridge. Jack McGrandle, a widower, is trying to rescue his one set of keys from their precarious perch on a ledge of the bridge.
Saddened by his only child's-David's-estrangement, he has been trying to convince himself to take a positive plunge: into matrimony with the woman he's been dating for nearly two years. Half a continent away, Mary's daughter, Anna, is finally discovering that her mother was right; her current boyfriend is not good enough for her. Anna packs her bags for San Francisco. Without question, Mary knows that Jack, David, and Anna deserve a second chance at happiness.
Of course they do!Yet there is one lesson that someone as kind-hearted as Mary needs to learn. She, too, deserves to be happy. And maybe, just maybe, her own second chance is waiting.
