Chrysanthemum by Kevin Henkes
Chrysanthemum has the perfect name, or she thinks she does. On her first day of school, the students all make fun of her 13 letter-long name (which is half of the alphabet!) and the fact that she's named after a flower. Chrysanthemum begins to hate her name, until she meets a teacher with an equally "weird" name.
I really like Kevin Henkes. His stories are full of great illustrations, good messages, and wit. While Chrysanthemum is written for children, adults can find some humor in Henkes' story as well. Chrysanthemum is a fun and colorful tale!
