Students in grades 2 and up played Musical books with @CGrabenstein novels. We rotated books that many people & opened up the text to search for examples of ‘excellent writing’. Was a lot of fun and great prep for Author Day 2025! #KeepThemReading @LincolnWPS @wyckoffschools

When I visited Heritage Heights Elementary in Buffalo I might've had a few tears in my eyes before I started my presentation because the music teacher and kids surprised me with a wonderful welcome and celebration of Stinky's Stories! This is the school that replaced Sweet Home Elementary in Buffalo where I was a student K-4th. @HarperChildrens

Tomorrow is the big day. Maybe even historic. The final Lemoncello book, MR. LEMONCELLO'S FANTABULOUS FINALE will go on sale wherever books are sold. (It will also give you something fun to do while we all stress over that even bigger thing happening tomorrow!) @randomhousekids
