It's a choose your own adventure book that marries the past, the future, and one of the worst human beings in the history of the world. (See, look on the bright side Wu-Tang Clan: at least it was Martin Shkreli and not Adolf Hitler who shelled out $2 million for your album). In Killing Hitler With Praise And Fire: Choose Your Own Horrible History the reader plays a time traveler from the year 2525 whose decisions lead to over a 100 different paths towards either killing Hitler, or eliminating him prior to his rise in power to (theoretically--don't discount the butterfly effect!) make the world a better place.
Author Matthew Hutchins has developed storylines in 13 different time periods for adventurers to explore. Victorious outcomes "range from the standard shoot Hitler in the face to the darkest Lovecraftian horrors."
