Henry (and his heart) are perfectly happy playing indoors. But Henry's mom encourages him to go for a walk outside. Soon, Henry's heart starts beating faster. Is Henry riding a rollercoaster? Is he doing jumping jacks? What could be making Henry's heart beat faster?

In this engaging, informative story, children learn about the many ways the heart functions within the body, and how what we see, hear, and feel can directly affect our heart rate (like falling in love with a puppy!). Henry's Heart leads him to the best gift ever—woof woof!
