Two quarrelsome ducklings engage in a bit of sibling rivalry in this lighthearted picture book for little readers.

Olivia and Lily might be twins, but they are not the same! Olivia likes to "jump in the mud," run around, and quack so everyone can hear, while Lily prefers studying and daydreaming. Though they go their separate ways, the twins can't stand to be apart for long. An adventure ensues, including a frightening tumble, but all ends well. The ducklings realize that while sometimes they are the same and sometimes, they are different, one thing is certain: they are "always twins."

Teri Weidner's watercolor art is the perfect accompaniment to this truthful story about sibling relationships for young children.
