NEVER IN A MILLION YEARS HAD GRANT EXPECTED THIS. His late wife, Ally, speaking on a memory videotape she'd left behind, was actually suggesting he start dating. "Date?" Grant thought aloud. "Who would I date? Who wants a widower who lives on a principal's salary and has three daughters?" Clearly anticipating his reaction, Ally said into the camera, "I know you're going to sit around for weeks saying you wouldn't know who to ask if you wanted to go on a date. I've thought this out, too." She leaned forward in the chair. "Jenna," she said softly. "I want you to date my best friend, Jenna. And, Grant, I think you'll fall in love with her."
