I’m not sure how long the pricing for this book will last, but currently the Kindle Edition of Diary of a Wimpy Kid, The Third Wheel is just $1.99. My son just started reading this series and he is just in love with these books. He thinks Greg Heffley is just so funny! This is the 7th book of the series and a fun addition to your kids’ summer reading. Remember, you can read this book on your Kindle or use a Kindle App on another tablet.
