Let's make this birthday one to remember.

87 years old (Born on December 23, 1937)

Happy Birthday, Avi! Another year older and wiser—though your characters might argue otherwise. From medieval mysteries to daring adventures at sea, you've given us countless reasons to stay up past bedtime with a flashlight under the covers. Winning that Newbery Medal in 2003 was just icing on an already delicious literary cake.

May this birthday bring you as much joy as Crispin found freedom or Charlotte Doyle discovered courage aboard ship. Keep inspiring young readers (and those of us who refuse to grow up) with stories full of humor, heartache, and hope—we can't wait for your next chapter!
