Unsinkable! (Hardcover, Turtleback Scho)

A spinoff from the highly successful Rookie Readers, this series teaches and encourages the development of good character. Each book in the series focuses on an important decision-making trait or skill, such as cooperation, responsibility, and fair play. The main characters are three, second-grade friends who live on the same city block and are called the Corner Kids. In each book, the friends -- Alex, Gabby, and Three J -- have a different adventure that challenges them to make thoughtful choices and to learn from their mistakes.

Alex doesn't think he'll ever be able to swim to the end of the pool without stopping. But with some help and encouragement from Three J and Gabby, he proves to be the most unsinkable one of all.
