Grandpa's Heart is a children's book that was written to help kids understand how the heart functions. Anthony and his Grandpa love swimming and Anthony is learning how to swim on his own. One day Grandpa can't come over because he woke up with heart issues and had to go to the hospital. Anthony's dad explains to him what is happening to Grandpa's heart by relating it to how a pool works and how the pool pump keeps the water clean. Over time Grandpa gets better and Anthony works hard to learn how to swim and surprise Grandpa when he comes home.
