Willimena rules!

Tina, Willimena's know-it-all big sister, advises her to smile and be nice, but a smile and nice won't get you very far if the class bully jumps in your face.

Willimena determines to do something to put mean Irene, the class bully, in her place after she pushed Willimena to the ground.

Willimena Thomas, worried that she will not get any Valentine cards from her classmates and friends, takes her sister's advice and sends herself some cards, but her troubles begin when she gets carried away--as usual.

When good-hearted third-grader Willimena spends her Girl Scout cookie money on lunch for some friends in need, she tries to creatively earn back the money she spent; ultimately she must face the consequences of not being responsible with the money.

Willimena gets into mischief over spring break, frustrated at the amount of attention her cousin Teddy is getting.

When third-grader Willimena loses the class pet, her teacher helps her to understand that responsibility means doing one's best, and that animals can't always be controlled.

Third-grader Willimena is unhappy when she is rejected for the leading role in a school play and instead is given the role of a tree in the play.
