Description The laugh-out-loud adventure features Lucy and her goofball brother Andy, as the Paleo pair take on a wandering baby sibling, bossy teens, cave paintings, and a mammoth hunt. But what will happen when they encounter a group of humans? Humorous and entertaining, Jeffrey Brown's signature comical touch enlivens the scientific and historical content, including a special paleontologist section that helps to dispel common Neanderthal myths.
