When choosing The Circus, I had already noted both the short length, and the fact that it was labeled as number 1 in the Choose Your Own Adventure series. This was fairly unusual, since most of the other Choose Your Own Adventure books were longer, and the Abominable Snowman is usually labeled as first. The reasons for both of these became apparent as soon as I began reading the text. The Circus is apparently the first in a separate line of Choose Your Own Adventure books from the main line—one aimed at an even younger audience than the main line, which is already marketed towards young children. As such, the material within is even more family-friendly, the text is even larger, and there is far less content.
Reading through The Circus overall was uninteresting for someone outside the target audience, since as a book targeted for small children, there was much sanitization. The “adventure” aspect is severely dumbed down by several factors. Primarily, it has become impossible to die, or otherwise end your adventure in more than a mildly unpleasant manner. The only truly BAD ending in the entire book is the one where the main character is bitten by a baby bear. There are a couple other endings that end abruptly, suddenly stopping your adventure (specifically, the “It was all a dream” and “Keep your eye on the bear!” endings), but otherwise there is no such thing as a bad ending. Notably, even in the “Keep your eye on the bear!” ending, wherein your uncle Harry is attacked by a bear, no one dies, and Uncle Harry escapes completely unharmed, and even relatively unfazed by the encounter. As a result of the main character’s apparent invincibility, the entire story becomes a simple wish-fulfillment of a child’s desire to visit the circus and see the goings on behind the scenes. In several endings, the main character miraculously develops the skills to become a circus performer—apparently overnight. Many of the tropes that a veteran reader of Choose Your Own Adventure books has come to expect (such as aliens, or secret societies) are also absent—with the notable exception of the standard “it was all a dream” ending. It is also notable that the main character is always depicted as a young male child, as opposed to most of the more “advanced” CYOA books, where the main character is almost always depicted as androgynous.
The entire book seems to function in a less webbed out fashion, like most CYOA books, and instead has a more circular flow (although not to the point of, say, the carousel path in "Twelve Blue"). Many paths lead back upon themselves, guiding the reader back to certain paths. It is specifically very easy to end up on the “Clown” path, and there are several ways to end up on the Lion Tamer path. Interestingly enough, there is a specific ending that gets its own epilogue, a small footnote at the back of the book explaining how the infamous Charley the Horse trick is done (a trick where a horse appears to be doing basic math). This ending is, suitably, difficult to end up on.
All in all, The Circus seems to be indicative of many of the other smaller “CYOA Lite” books, some of which seem to be shortened versions of “full-size” CYOA books—smaller, and generally less branching and dangerous.
