Edit Dec 2016 (spoilers): So there’s been a lot of rumbling about how this book is ableist and stuff and I think that’s probably why I had problems with the end of it, it felt like such a cop out for her to not be allergic to everything, for it to be due to her mum having a severe mental disorder. I would’ve much preferred to see how the couple got on with their relationship despite Maddie having SCID. I liked this book a lot but it has a lot of problems and if you’d like to read more here is a post about it: http://disabilityinkidlit.com/2015/09/04/review-everything-everything-by-nicola-yoon/
Edit March 2017: here is another review where the reader has a similar illness https://www.goodreads.com/review/show/1444235181
Oh man what a wonderful book, a wonderful contemporary book that has so much diversity in it and problems and all that stuff but also made me feel so happy.
Maddy is completely allergic to the world. She can’t leave her house, she can’t meet new people and she has to been home schooled over skype. One day she has some new next door neighbours who intrigue her so much that she wants to leave her house and discover what awaits outdoors, but her mum is completely against it and so Maddy ends up emailing the boy next door late at night.
I loved that the MC was a biracial Asian/African American, like that’s something that you don’t see a lot in novels and it was just great to read. Olly was just wonderful, I need an Olly in my life.
