Young adult. Kate devoured this book and I devoured it after her. Maddy is a girl in a bubble. She is ill and can never go outside or risk death so she lives inside with her mom and her nurse and has done so for 18 years. She is happy and content with her life. Then a cute boy moves in next door and she falls in love. They start to Instant message each other. She wants to live her life and experience more. So she takes a risk and runs away to Hawaii. She ends up sick and in the hospital and eventually back home with her mom. But tests run at the hospital reveal she is not so sick after all. Spoiler alert - twist at the end. She is not sick and does not need to live in a bubble. Her mom told her that (and believed it?) because when she was a baby her dad and brother died in a tragic car accident. This book is ultimately all about love. Not just between Maddy and the cute boy, but also Maddy and her mom. Her mom didn't want to hurt her but really just wanted to protect her. Written really well. Very good book about living and loving.
