Brianna Caplan Sayres

Brianna Caplan Sayres used to tell her second graders, “When I grow up, I’m going to be a writer.” “But you are grown up, Mrs. Sayres,” her students would protest. Well, Brianna is still not quite sure she’s grown up, but she has grown into a writer. Brianna’s picture books include the Where Do Diggers Sleep at Night? series, illustrated by Christian Slade, Tiara Saurus Rex, illustrated by Mike Boldt, and Why Did the Chicken Cross the Road?: A Hardboiled Mystery, illustrated by Mark Fearing. Can you guess what the next diggers book will be? If you said, Diggers Love Their Grandparents (coming in 2026!), you were right! 
 
Brianna has recently returned to her hometown, Seattle, Washington, where she loves to have adventures with her two wonderful boys. You can visit Brianna on the web at briannacaplansayres.com or facebook.com/authorbrianna
