Christine Day (Upper Skagit) grew up in Seattle, nestled between the sea, the mountains, and the pages of her favorite books. Her debut novel, I CAN MAKE THIS PROMISE (Harper), was a best book of the year from Kirkus, School Library Journal, NPR, and the Chicago Public Library, as well as a Charlotte Huck Award Honor Book, and an American Indian Youth Literature Award Honor Book. Her second novel, THE SEA IN WINTER (Harper/Heartdrum), is coming to shelves on January 5, 2021. She also wrote the forthcoming SHE PERSISTED: MARIA TALLCHIEF (Philomel), an early reader biography in a new series inspired by Chelsea Clinton's bestselling picture book. Christine lives in the Pacific Northwest with her husband. Her work is represented by Suzie Townsend at New Leaf Literary & Media, Inc.

Kaitlyn Sage Patterson grew up with her nose in a book outside the Great Smoky Mountains National Park. After completing her M.F.A., she moved to South Korea, where she taught English and started writing her debut novel. THE DIMINISHED will be published by HarlequinTEEN in April 2018, followed by its sequel in 2019. When she's not staring off into space and trying to untangle some particularly troublesome plot point, she can be found in her kitchen, perfecting the art of the macaron; or at the barn, where she rides and trains dressage horses; or with her husband, spoiling their sweet rescue dogs.
