The Witching Hour — Susan Laine

When teenager Perry Green witnesses his adult neighbor, Seth Moore, crying in his car late one evening, Perry sets out to console the man he's spent many a year fantasizing about. But Seth's personal crisis takes a backseat when a magical grandfather clock sends the two of them back in time to witness a pivotal moment in his past. As Seth and Perry work to solve the problem, romance blossoms -- or it would, if Perry could just convince Seth that love surpasses time itself.
