Choose Your Own Adventures are stories that allow the reader (or writer) to determine the direction that a story takes through multiple decision making opportunities. I enjoyed these stories when I was younger and am thrilled to see that they are still alive-and-kicking.

Mr. Larry Ferlazzo, a teacher of Beginner, Intermediate, and Advanced English Language Learners (as well as native English speakers) at Luther Burbank High School in Sacramento, California, has put together an impressive list of Choose Your Own Adventure websites... You can take a look at the entire list here or see a sampling below. By the way, because he is teacher of students who are learning a second language he often includes information regarding the level of accessibility of each site - you can choose to use this information or ignore it.
