Desmond and Andres visit a scary roller-ghoster in this eleventh haunted adventure in the Desmond Cole Ghost Patrol series! The Kersville Amusement Park is always a good time, but it also gives a new meaning to the term "thrill rides." That's because, in addition to being a popular destination for heart-pounding fun, the park is also just a little bit haunted. Join Desmond and Andres as they try to enjoy their day at the amusement park while being chased by ghosts! Warning: You must be this tall to read this book. With easy-to-read language and illustrations on almost every page, the Desmond Cole Ghost Patrol chapter books are perfect for emerging readers.
