  Now, an audio book!
Imagine a honeymoon aboard a flying Mississippi River boat.  
Then, imagine Mark Twain being a guest! 
Imagine him being a mentor to 11 year old Nikola Tesla.
Unwelcome passengers include 
a vampiric Benjamin Franklin, 
an insane Abraham Lincoln,
a vengeful General Sherman,
a pursuing Captain Nemo aboard his Nautilus, 
and a thieving Thomas Edison.
Add to that company: 
Ralph Waldo Emerson, Horace Greeley, 
Ada Byron (inventor of the 1st computer language a century before computers), 
Margaret Fuller, first American woman foreign correspondent ...
Well, things get interesting!

Hurricane Katrina made landfall this day in 2005 as a Category 4 storm 
but still remains the worst natural disaster in U.S. history.
What would have been its aftermath if supernatural and undead predators existed?
