Lauren Ipsum is a whimsical journey through a land where logic and computer science come to life.
Meet Lauren, an adventurer lost in Userland who needs to find her way home by solving a series of puzzles. As she visits places like the Push & Pop Café and makes friends with people like Hugh Rustic and the Wandering Salesman, Lauren learns about computer science without even realizing it—and so do you!
Read Lauren Ipsum yourself or with someone littler than you, then flip to the notes at the back of the book to learn more about logic and computer science in the real world.

I feel I should warn you: You won’t find any computers in this book. If the idea of a computer science book without computers upsets you, please close your eyes until you’ve finished reading the rest of this page.
The truth is that computer science isn’t really about the computer. The computer is just a tool to help you see ideas more clearly. You can see the moon and stars without a telescope, smell the flowers without a fluoroscope, have fun without a funoscope, and be silly sans oscilloscope.
You can also play with computer science without you-knowwhat. Ideas are the real stuff of computer science. This book is about those ideas and how to find them. In fact, most of the characters, places, and thingamajigs in Userland are actually based on those ideas. Check out the Field Guide at the back of the book to learn more about them!
