So I have reached into my magic hat, and the winner of the Peter and the Starcatcher Broadway ticket is Karen B. Schwartz! Karen imagined a prequel to Beverly Cleary's fantastic "Beezus and Ramona":
Ramona enjoyed making her sister Beezus's books beautiful by drawing pictures in them with bright blue marker. Which was why it was so puzzling that Beezus locked all her things in her room. Ramona just had to try harder to show Beezus how fun she could be.
Congratulations Karen - just send me your email address and I'll forward you the voucher for two tickets!
Thanks to everyone else who left (and thought of) great prequels to their favorite kids books!
