If you get grossed out by blood, this one probably isn’t for you. But if you’re like me and find it fascinating, you’ll enjoy this book by a British journalist with an especially personal connection to the subject. I’m a big fan of books that go deep on one specific topic, so Nine Pints (the title refers to the volume of blood in the average adult) was right up my alley. It’s filled with super-interesting facts that will leave you with a new appreciation for blood.
