Escape from Tenopia #1-4 Bookography
Written by Richard Brightfield, Created by Edward Packard, Illustrated by David Perry
These are, pretty much, Choose Your Own Adventure books; Created by Edward Packard, whom started the whole Choose Your Own Adventure series. The big difference, is that while there are many paths/choices you can make, there is only one ending (The End), and you have to make all the right choices to get to it.
Some personal notes regarding #4 Star System Tenopia; While I was scanning in this book. I put too much pressure on the spine, trying to flatten it out for a good scan... chunks of the pages separated from the spine of this book, and there are a few pages where you can see the pages coming apart in the scan. I still did the best I could scanning in the entire book, but a few of the pages in this look funky (you can still read it just fine). This book itself is nearly 28 years old...
