The second installment of Rocket and Groot's adventures, penned by Tom Angleberger, follows much of the structure that made the first book, Planet Strip Mall, entertaining and attractive to readers who are just starting to take the risk of reading chapter books. Although it is a little over 250 pages long, there is a lot of repetitive text which will allow at-promise readers to feel comfortable with the length. Again, readers will marvel and use their imagination and context clues to figure out the different meanings they can infer from the font and size of the phrase "I am Groot!". Many more characters are introduced in this novel, and as always, there is a distinct font for each, making it easy for the reader to identify whose dialogue they are reading. This adventure takes Rocket, Groot, and Veronica into planet HappyHappyFunFun where computer driven cars are totally out of control and it's up to our heroes to figure out why and stop the mayhem. Readers will be invited to use their visualization skills as car chases, narrow escapes from death, and life-saving gadgets are described by their "sounds". A lesson in how to speak "truck-driver" adds to the fun and craziness of the adventure, as this is how the out-of-control-vehicles communicate with each other and our heroes. Funny and colorful illustrations add to the awesomeness of this read.
