There are basically two kinds of time travel stories. There's the Sprague DeCamp/Robert Silverberg kind of story, full of large, historymaking events, and the Time Patrol to protect the continuum, and knowledgeable time travelers making things happen. And there's the Jack Finney kind of story, about ordinary people dealing with small-scale events in out-of-the-way towns and trying hard simply to cope with things that happen to them willy-nilly. Dickinson has written a warm, funny, affecting example of the second kind of story. Josh Winkler is a somewhat feckless artist living in Euclid Heights, Illinois, where crosswise shortcut paths known as "perp walks" disturb the town's gridded layout. He's married to a doctor, the sister of his brother Kurt's best friend when they were kids, before her brother drowned in the town pool and Kurt suffered permanent brain damage. Their fifteen-year-old daughter, Penny -- the best-drawn character in the book, I think -- is about all that's still keeping them together. Then Josh gets caught riding his bike in a storm on one of the perp walks and is tossed fifteen minutes into the past. But young Constance, who appears soon after, has a worse time of it, dragged into our own era from 1908. Can she get back? Can she adapt to our world? And what happens if someone else becomes an unintentional time traveler? Dickinson's style is quiet and thoughtful; he almost lets the story tell itself. An excellent piece of work.
