Walking a Fine Timeline

Sherman had no future, until he finds himself in the future, accidentally kidnapped by Dr. Serendipity Brown, inventor of time travel. She hires him as her assistant, since Sherman has the one quality Serendipity lacks: common sense. Gallivanting about in an experimental time machine, they soon find themselves stranded in the year 1851. Can Dr. Wendell Howe, the unobtrusive Victorian gentleman who claims to be a Temporal Anthropologist from the twenty-seventh century, help them get back home? Will the Institute of Time Travel Enforcers find and arrest Wendell for breaking their rules if he does? Can Serendipity perfect her time machine? And hardest of all, can Sherman keep man-crazy Serendipity out of trouble?
