The True Meaning of Smekday by Adam Rex, 423 pages
When the Boov aliens invade Earth, 11-year-old Gratuity (her friends call her Tip) Tucci is left on her own to track down her mom, driving a little hatchback from Pennsylvania to Florida with only her cat, Pig, for company. But when the car breaks down, a Boov named J.Lo soups up the car and joins Tip on a cross-country alien-dodging trip that takes them to Orlando's Happy Mouse Kingdom and Roswell, New Mexico, among other places. This is a fantastic, and fantastically funny, adventure, full of heart, history, and the odd juvenile joke.
What made this experience all the better was that this time around, I listened to the audiobook with my family on a road trip of our own. Read by the wonderful Bahni Turpin, Tip and J.Lo came to life in our car, and left the whole family giggling on a long drive that otherwise would have been filled with complaints. A great experience for all of us.
