Everything, Everything was a book that kept me reading. I was fascinated by Madeline's life--it's hard to imagine never being able to interact with the outside world because of a life-threatening disease, but that is exactly what Madeline has experienced for the last 18 years. Madeline as a complex immunodeficiency disease that makes her a "bubble child". The only people she has physical contact with are her mom and her nurse, Carla. Madeline's mom is a caring, competent medical doctor who has devoted her life to protecting her daughter, and Carla is a warm, loving influence in Madeline's life, serving as her daytime nurse and only friend. Yoon helps us to know Madeline and her life through her thoughts, and her writing--in her notebooks, in book reviews, in emails and IMs, and in the personal definitions she creates for words in her self-made dictionary. 
 When Olly, a teenaged boy, and his family move into the vacant house next door, Madeline naturally becomes interested. She watches the family from her window, learning as much as she can about them from what she can see and hear from their house. Eventually, Olly is able to capture Madeline's attention and shares his email address by writing it on his window. From there, Madeline and Olly become the best of friends, and eventually more, as Madeline starts to risk her health in order to actually LIVE her life. 
 Madeline's and Olly's story is a captivating one that many teens (and adults) would have a hard time putting down. Well-written and thought-provoking, it's a book I won't forget anytime soon!
