Viv and Sanjay are the Inside Scouts! Together, they help animals. They have a cool superpower -- they can shrink super small. When a lion with a leaky heart needs help, the Inside Scouts know what to do! They put on their suits, grab their tools, and get really small. They go inside the lion to find the leaky spot. And they fix it together!

This series introduces beginning readers to the human body through mammals with similar anatomy -- and it does so in really fun ways! In this first book, readers learn about the circulatory system as Viv and Sanjay fix the lion's heart! With color-coded speech bubbles, easy-to-read text, and light nonfiction content, these engaging STEM-themed stories are the perfect fit for new readers!
