It isn't as though Moxy isn't grateful for all her Christmas presents. She's just not so thrilled that she has to write 12 thank-you notes. Not to mention that she promised her mother they'd all be done by today. And if they're not - well, there will be "consequences". Namely, Moxy won't get to leave tomorrow for the vacation of a lifetime. (A trip to California to attend a Star-Studded Hollywood Bash with the father she hasn't seen in three years.) Moxy's wild schemes to get her thank-you notes done in time are clever, poignant, and always hilarious.

In this hilarious third installment about everyone's favorite tween procrastinator, Moxy Maxwell is set to make her piano debut, playing a duet of "Heart and Soul" with her little sister, Pansy. Its too bad she has no time to practice. Between costume fittings, trying on her crown, warming up her voice, and putting on her stage makeup, Moxy cant possibly worry about the actual performance. But soon its upon her, and Moxy feels something shes only felt once before in her entire life: nervous! She's not sure she can go on. Of course, Moxy is Moxy and she rises to the occasion brilliantly.

Here's the first audiobook in the hilarious Moxy Maxwell series, which includes Moxy Maxwell Does Not Love Writing Thank-You Notes and Moxy Maxwell Does Not Love Practicing the Piano. It wasn't as if Moxy Maxwell hadn't tried to do her summer reading. She and Stuart Little had been inseparable all summer, like best friends. If Stuart Little wasn't in her backpack, it was in her lap...or holding up the coffee table...or getting splashed when Moxy went swimming. But now it's the end of August - the day before fourth grade. And if Moxy doesn't read all of Stuart Little immediately, there are going to be "consequences". It may look like Moxy is doing nothing, but actually she is very busy with a zillion highly crucial things, like cleaning up her room (sort of) and training her dog and taking a much-needed rest in the hammock. Of course our heroine does manage to finish her book, falling so in love with it that she finds herself reading under the covers with a flashlight, late into the night.
