The second book in an exciting new picture book series focused on the science of the body from writer Stacy McAnulty, who leaves the solar system behind and takes readers into the human cardiovascular system with the help of a vampire duo.
Welcome to "I Don't Vant to Suck Your Blood" smoothie shop, where all products are 100% blood-free! Good news for humans, but bad news for a certain vampire who just wants a pint of O-positive.

This funny and fact-filled picture book is all about blood: where it's found, what it does, how it travels, and why vampires shouldn't drink it. From the four chambers of the heart to the platelets that clot your blood when you scrape your knee, everything you want to know about the cardiovascular system is right inside these pages. Just watch out for thirsty vampires.
