Gaze upon its awesomeness!
Here's the synopsis according to Atria Books:
1898. New York socialite Emma Harlow agrees to marry well-to-do Montgomery Gilmore, but only if he first accepts her audacious challenge: to reproduce the Martian invasion featured in H.G. Wells’ popular novel The War of the Worlds. Meanwhile in London, Wells himself is unexpectedly made privy to certain objects, apparently of extraterrestrial origin, that were discovered decades earlier on an ill-fated expedition to the Antarctic. On that same expedition was an American crew member named Edgar Allan Poe, whose inexplicable experiences in the frozen wasteland would ultimately inspire him to create one of his most enduring works of literature.
