I have selected three books for the occasion:
1. Shakespeare's Globe: An Interactive Pop-up Theatre, published by Candlewick. Okay, it's not so much a book, but it is book-like. For those who wish to carry the "Twelfth Night" theme in dramatic fashion.
2. Three Kings Day: A Celebration at Christmastime by Diane Hoyt-Goldsmith and Lawrence Migdale, for those who want to note the day in an ecclesiastical fashion.
3. Martin's Big Words, by Doreen Rappaport, illustrated by Bryan Collier, for those who want to celebrate the whole month, and not just today!
