Everyone knows you can't time-travel. But the rules change in Silverville, where anything is possible. Combine ley lines with a mysterious privy fungus and you might end up anywhere from ancient Egypt to the Wild West or into the future. Add in an almost-zombie and a pig that can sing "Happy Birthday," and you're in for a wild ride - if the tour guide can just work out the kinks. This is book three of the Silverville Saga of books.
