"Let's have a Fest!" written in rhyme has a moral theme developed around the cast of Fun Time Flower characters in their daily life. The Fun Time Flowers books are written interactive, inviting the reader to join the Fun Time Flowers in their activities and become part of the story. Aulbach has also written a companion ABC book with excerpts from the story book, and a Character book that introduce the characters and their favorite activities. "Let's have a Fest!" follows a day in the life of the Fun Time Flowers Family. The Flowers and their companion pets are youthful, energetic, and cheerful. The theme of the story gently teaches, through the example of Fun Time Flowers, the values of caring, sharing, and getting along, while enjoying the precious and wonderful gifts of life, nature, and the love of one another.
