When the power goes out and his only entertainment option is to read, Alex feels certain that he will die of boredom. Enter Zora, the new girl next door who is determined to go on an adventure. Zora discovers that Alex's old picture book, The Great Alphabet Adventure, is mysteriously blank and that their job as explorers will be to find the missing letters and return them to the book. Alex's ordinary room begins to reveal extraordinary hidden worlds and a cast of colorful and wacky characters who lead Alex, Zora and the audience on a treasure hunt through the alphabet. In the end, Alex and Zora learn something about the fun of reading and about the value of friendship."--Page 4 of cover.
