Refe and Susan live in the suburbs of Chicago with their four children, Boris the dog, and a herd of plastic dinosaurs. The Tumas began cataloguing their dinosaurs' antics in 2012, creating Dinovember and igniting the imaginations of hundreds of thousands of children--young and old--across the world.

Refe and Susan are the authors of the What the Dinosaurs Did picture book series, including What the Dinosaurs Did Last Night, What the Dinosaurs Did At School, and the upcoming What the Dinosaurs Did on the Night Before Christmas.

Refe’s debut Middle Grade novel Frances and the Monster is now available. Frances and the Werewolves of the Black Forest will be published by HarperCollins on August 22, 2023. Preorders are available now.
