Jacob's Missing Book by Sarah and Ian Hoffman

Noah is confused about Emily's family, so he asks her―who’s Pop and who’s Dad? Jacob knows just how to explain, but how can he? The penguin book isn't in the library anymore! As the day goes on, everyone is still talking about the mysterious missing book. Ms. Reeves tries to explain why the book is no longer in the library and what all the fuss is about. In the meantime, Jacob hatches a plan to tell the story about Emily's family.

This book cleverly weaves two critical societal issues into one story ― book banning in schools and LGBTQ+ rights. And, who is caught in the middle of all this? Kids who are eager to see themselves and their families in books, feel safe with their experiences, and understand that they are loved and supported.
