A blast from the past. . . My review from March 21, 2008:
The True Meaning of Smekday
by Adam Rex, 423 pages, 2007.
Winner of the SF/F Elementary/Middle Grade category of the Cybils. There is a great description of it there. Basically, it is hilarious. But what do you expect with a girl named Gratuity, a cat named Pig, and an alien named J.Lo? Their illegal hovercar is only the start! Recommended to fans of The Hitchhiker's Guide and/or humans ages ~10+. A must-read.
I recently re-read this one. I had forgotten just how funny it was! Not only are there really funny things happening, but Tip's voice is so snarky. On top of that you get to see Tip and J.Lo's relationship change as they come to understand one another better. I think it's a very relevant story as far as living in these crazy times.
Also, I heard that Adam Rex is writing another novel, however this new one will be sans illustrations. I'm looking forward to it!
