Tars Tarkas of Mars is an inventive gamebook in the style of the best CYOA of the 80s. It has a lot to recommend it, including a gripping if fast-paced story and a professional look and great game system. Also, the price is right.

You'll notice that this review has two stars. The problem that I've encountered is that this hyperlinked epub file is broken. The links seem to be layed out properly, but sometimes you are taken to a section that you did not click, leading to loops in the game. I am not certain that the book can be completed as is. If this problem is fixed, then it will get a far higher review.
