Ephie and Celia Risho published their first novel this summer, but the father-daughter duo is back to world-building and writing — this time about dragons.

Celia, now 12, was an 8-year-old attending Hawthorne Elementary School when her bedtime reading routine morphed into a years-long collaboration with her dad. Her third grade teacher tasked the class with writing a short story, but Celia was interested in creating something bigger.

“Phoenix Rising (The Elementalists, Book 1)” follows a 12-year-old heroine’s journey navigating a world with pixies, wizards and other fantastical creatures. It’s primarily geared toward young adults and children, but Ephie said he’s heard from adults who loved it.
