When Brenda is a very young girl, her mother takes her to the YMCA near their home so that Brenda can learn how to swim. While she is on the side of the indoor pool, another child challenges her to a race. Brenda agrees, not knowing that she could be in danger. The water is very deep, and Brenda doesn't really know how to swim yet, so she sinks down into the deep blue water. Luckily, there is a lifeguard nearby who jumps in and pulls her to safety. But now Brenda is sad and afraid of the swimming pool. Even so, she continues to take swimming lessons, learning how to respect the water. As she grows up, she learns how to have fun while swimming and even begins to teach others how to swim. In this children's story, a scary incident helps one little girl begin a lifelong journey of swimming and water safety and helps children understand the importance of knowing how to swim.
