I spent 20 years homeschooling my two boys and NEVER encountered this book. It is one that they would have enjoyed. Milo is bored. There isn't anything interesting happening in his life. One day he comes home from school and finds a package. Opening it up, he finds a tollbooth. He takes a ride through the tollbooth and finds a strange and mysterious world. It is full of figures of speech, puns, and other hilarious word play. Much that happens is the literal meaning to words. For example, Milo and some new friends he meets on his journey go to the island of Conclusions. They reach it by jumping to Conclusions. The whole book is witty and funny. I'm not sure I would have understood the book as well if I had read it as a child. However, I highly recommend it for both children and adults.
