This book is more for the people who loved Tom Sawyer and Huckleberry Finn, and just have to have more of them. In this book Tom, Huck, and Jim go on an adventure to the Sahara desert. Other then the doctor in the first chapters, it is only the three of them. Tom often argues with Jim and Huck about random facts, Tom is right but is defeated by being double teamed by Jim and Huck. While this is funny the first few times it gets rather old after the fifth argument. You could say this book is The Adventures of Huckleberry Finn without Huck and Jim leaving the raft and the inclusion of Tom.
It was funny at times, and it is free. If you love Tom Sawyer and Huckleberry Finn, you could love this book. If you hated the two books stay away. This book could be skipped, but if you just have to revisit these characters the choices are very limited.
