I bought this book because I forgot my earbuds and I needed something to occupy my time on a long flight. This book is as terrifying as it is captivating. What's more than being the kind of book you plow through in a day is it has literally saved lives. This author raised so much awareness for her illness that it led to other diagnoses and treatment. Don't start reading at night because you'll stay up all night ripping through pages as she deteriorates and races against her failing mind.
