Exchange is a new alternate history novel by Dale Cozort.
Exchanges have become ‘routine catastrophes’, like a hurricane or a major earthquake. Having their town pop into a wild, dangerous alternate dimension for two weeks is hardly routine for the people of Rockport though. One of them, Sharon Mack, has to fight her way through threatening animals, a brutal street gang, escaped convicts, and the "Church of the Second Chance" to get her daughter back.
Exchange has a rich, unique setting. It has strong, colorful, ambiguous heroes and villains. It has an intricate plot--wheels within wheels as one character puts it--that should keep you guessing until the end, as powerful ambitions clash over the future of both realities.
