I talk with prolific children's author Megan Hoyt on her new non-fiction picture book, The Greatest Song of All: How Isaac Stern United the World to save Carnegie Hall, published by Harper Collins Children's Books' new imprint, Quill Tree Books less than two weeks ago. Megan is also author of Bartali's Bicycle, published last year with the same publisher. Three more non-fiction picture books are forthcoming, also with Quill Tree: A Grand Idea: William Wilgus and his Grand Central Terminal, and Kati's Tiny Messengers: How Dr. Katalin Kariko Developed an mRNA Vaccine to Fight Covid 19.

Mel Rosenberg is a professor of microbiology (Tel Aviv University, emeritus) who fell in love with children's books as a small child and now writes his own. He is also the founder of Ourboox, a web platform that allows anyone to create and share awesome flipbooks.
