About Me

Greetings! I am Gloria Koster, a children’s author and librarian. For many years I worked full-time at a wonderful Connecticut elementary school. 

Currently I am a member of the Children’s Book Committee of Bank Street College of Education. Each year we read hundreds of new titles to select the very finest choices to be included in our Best Books guide.

My husband Eric and I have three adult children and five grandkids. We split our time between the beautiful Berkshire Hills of Massachusetts and New York City.We also love to travel, especially to France, where I continue to embarrass myself by stumbling over the elegant language. Quel dommage!

My first book, The Peanut-Free Café, was inspired by all the time I spent in a school lunchroom, watching a lot of fussy eaters and the challenges faced by kids with food allergies. Overdue: The Misadventure of Bob the Book is another example of “write what you know.” It evolved from my time as a school librarian. Some of my other titles include Little Red Ruthie (Albert Whitman), Mitzi’s Mitzvah (Kar-Ben), and Dance the Hora Isadora (Apples & Honey Press). And stay tuned for my forthcoming picture book biographies Bravo, Lenny Bernstein! (Astra/Calkins Creek) and Ona Šimaitė: Heroic Librarian of World War II (Capstone Press) plus Murphy and the Egg: The Old Eagle Who Became a Papa (Capstone Press).
