Project UFO is an odd book. It's not often in Choose Your Own Adventure that you can be unexpectedly "swept away into eternity" just by opening a door. There are severals endings like this throughout the book, and the reader will often wonder what happened to bring the adventure grinding to such an abrupt halt.
Nonetheless, there is fun to be had. Let your imagination roam outside the normal parameters of a book, outside even the boundaries of a regular Choose Your Own Adventure, to a place where the connectedness of your mind to everything that you have ever known can be, at times, your only lifeline to reality. Immerse yourself in an alternate life in which you have been in mental contact with an alien being named Freedo since you were five years old, sending messages back and forth as you grew. Now, your seemingly benevolent friend requires your help to battle a mysterious alien force that is not as friendly as Freedo.
As you enter further into Freedo's world of extraterrestrial espionage, you'll have to make hard decisions about whom to trust, both among humans and aliens. If you make your decisions with the right mix of courage and wisdom, you'll finish in a better place than you were when the story began.
Readers who are partial to R.A. Montgomery's unique writing style will likely revel in this story, while fans of Edward Packard might be puzzled by the odd narrative structure. Most kids who read this book wanting to find the fun will have their expectations met, albeit in offbeat fashion. I would give Project UFO at least one and a half stars.
