The power of this book is that (while reading it) it unwittingly transformed many of the foods I lifted to my mouth into a hidden poison, and I would flinch before I remembered that I am not allergic to any foods. My empathy levels were on full capacity, partly because I am such a good person I'm sure, but mainly because Sandra did such an effective job of describing her allergic reactions, her anticipation of allergic reactions, and her social anxiety about having allergic reactions. 
 She also provided an informative document about the lives of those who suffer from food allergies and some of the science behind it. Though I don't suffer from any food allergies (thank goodness), my mother is allergic to shellfish, and because I have often been considered her clone, I grew up with anxious faces staring at me when I decided to order the popcorn shrimp. Everyone feared I would develop the allergy as well. 
 The book was informational and suspenseful and witty and very self-aware. It's a good gift for families with children who suffer from food allergies.
