Anticipation and anxiety lead to gleeful exhilaration in this story of a father-son roller-coaster ride. A timid young boy is just barely tall enough to ride the DinoCoaster, so he joins his father for a fast-paced journey that takes them climbing, zooming, sailing, and lurching upside down, round and round, past a colorful cast of amusement park creations. When the roller coaster finally comes to a stop, the boy is ready for another ride...but his queasy father isn't quite as enthusiastic. Diane Adams' action-packed propulsive rhyme carries the reader along on a journey from fear to delight, accompanied by Kevin Luthardt's appealing, friendly amusement park dinosaurs.
