About Ultimate Ending Books
Remember the old Choose Your Own Adventure books of the 80’s and 90’s? They were cool. Fun. Sometimes even challenging.
But they weren’t always coherent.
Ultimate Ending books take Choose Your Own Adventure to the next level!
Each book in the Ultimate Ending series features exciting plots and detailed stories, with bigger worlds and richer characters. Best of all they feature clever riddles and challenging puzzles, and hidden within every story, one truly Ultimate Ending!
How They Work
CYOA Written with Kids AND Adults in mind!
Ultimate Ending books are geared toward children and teens, but with compelling stories and a writing style that adults would also enjoy. They contain only mild violence, and put an emphasis on creative problem solving. There are riddles to figure out, cryptograms to solve, and visuals based on artwork. Some solutions involve minor math equations. All of the solutions involve fun!
