Leo has a genetic disease called neurofibromatosis 1 (NF1), but it doesn’t keep him from fun activities. He also happens to have hidden superpowers — which come in handy when suddenly, the T. rex comes to life! Soon other strange events around the city put people in danger. Can Leo and his superhero dog, Clark, find the source of the attacks?

Find out why Leo is the perfect superhero for this adventure as he focuses on life beyond neurofibromatosis.

G.W. Page was diagnosed with a rare genetic condition called neurofibromatosis (NF) as a baby. Now at age 10, G.W. has an extensive team of doctors who routinely monitor him for new tumors or other NF-related problems, which can be very unpredictable. With his positive outlook and fierce courage, even as the youngest of his siblings, he sets a big example for his family about choosing how to react when things go wrong or when they are afraid. He loves playing sports, creating art, fishing, fantasy football, cooking with his dad, and being a goofball with his big sisters. When he grows up, G.W. hopes to become a professional sports analyst.
