Kate Prosswimmer Senior Editor Margaret K. McElderry

Kate Prosswimmer is a Senior Editor who joined the McElderry team in 2019. She’s enthusiastically acquiring a list of picture books, middle grade, and YA fiction and is excited to be working with a talented group of New York Times bestselling, award-winning authors including Amanda Foody, F.T. Lukens, Jon Graziano, Rebecca Barrow, Tola Okogwu, and Scott Reintgen to name a few. She previously spent five years at Sourcebooks where she had the privilege of editing a number of award-winning titles including Zoraida Córdova’s Brooklyn Brujas series, Jess Keating’s Shark Lady, and Jen Calonita’s Fairy Tale Reform School series. Kate is always down for a great mystery, isn’t afraid of books that will make her ugly cry, enjoys atmospheric and unusual settings, prefers middle grade stories that are both whimsical and earnest, looks for picture books that favor story over message or concept, YA that feels escapist in both contemporary and speculative genres, and stories across all ages that make the ordinary feel extraordinary.
