Peyton Grooms is the author of the series When Giants Roamed the Earth, as Grooms has always been fascinated by dinosaurs and the harsh environments they lived in. As a kid, Grooms struggled to find stories he really liked until he picked up Jack London’s The Call of the Wild off the shelf. He thought the story was wonderful: animals living in harsh environments and still fighting to see the next day. Jack London’s Books helped to inspire Peyton Grooms’ series When Giants Roamed the Earth. Grooms has had such a large imagination ever since being so young, and Dinosaurs captivated it more than anything. He has researched everything he could since the age of 4, from reading books to staying updated on the newest articles. Grooms tries to stay as close to accuracy as possible in his books, portraying Dinosaurs as animals more than monsters.
