I remember reading this as a child. Unfortunately, the only thing I remember is that I really liked the book. Guess that means I need to re-read and see for myself again, huh?

Cover blurb:

For Milo, everything's a bore. When a tollbooth mysteriously appears in his room, he drives through only because he's got nothing better to do. But on the other side, things seem different. Milo visits the island of Conclusions (you get there by jumping), learns about time from a ticking watch-dog named Tock, and even embarks on a quest to rescue Rhyme and Reason! Somewhere along the way, Milo realizes something astonishing. Life is far from dull. In fact, it's exciting beyond his wildest dreams!

I have purchased a copy of this for my Kindle, so will set this paper copy free soon.

Left on a table near the entrance. Enjoy!
