I found Killing Hitler With Praise And Fire on a list of grown-up CYOA at Goodreads and, though the ratings there were uninspiring, I followed a link to Amazon and checked out those reviews as well. Most of the positive reviews mentioned the novelty and nostalgia of finding a modern CYOA book. Other opinions ranged from “meh” to negative, with one interesting “review” in which the reviewer said nothing about the book except that it was not this “book”.
Note: it’s not available on Kindle.
