A love story serves as backdrop for The Map of the Sky when New York socialite Emma Harlow agrees to marry millionaire Montgomery Gilmore, but only if he accepts her audacious challenge: to reproduce the extraterrestrial invasion featured in Wells's War of the Worlds. What follows are three brilliantly interconnected plots to create a breathtaking tale of time travel and mystery, replete with cameos by a young Edgar Allan Poe, and Captain Shackleton and Charles Winslow from The Map of Time.
