You Don't Know Everything, Jilly P!

Alex Gino, the Lambda Literary Award-winning author of Melissa, is back with another sensitive tale based on increasingly relevant social justice issues.

Jilly thinks she's figured out how life works. But when her sister, Emma, is born deaf, she realizes how much she still has to learn. The world is going to treat Jilly, who is white and hearing, differently from Emma,

just as it will treat them both differently from their Black cousins.

A big fantasy reader, Jilly makes a connection online with

another fantasy fan, Derek, who is a Deaf, Black ASL user. She goes to Derek for help with Emma but doesn't always know the best way or time to ask for it.

As she and Derek meet in person, have some really fun conversations, and become friends, Jilly makes some mistakes . . . but comes to understand that it's up to her, not Derek to figure out how to do better next time--especially when she wants to be there for Derek the most.

Within a world where kids like Derek and Emma aren't assured the same freedom or safety as kids like Jilly, Jilly is starting to learn all the things she doesn't know--and by doing that, she's also working to discover how to support her family and her friends.

With You Don’t Know Everything, Jilly P!, award-winning author Alex Gino uses their trademark humor, heart, and humanity to show readers how being open to

difference can make you a better person, and how being open to change can make you change in the best possible ways.

Alex Gino does it again!! He has such a phenomenal way of writing about sensitive subjects in a way that is thoughtful and understandable to young readers. I really thought this book was only going to be about one thing but I love how he mixed in other subjects as well. Jilly loves to chat online with a group of kids who love the same book series. There she meets another kid who is Deaf. When her baby sister is born Deaf, Jilly wants to know everything she can and how she could help both her sister and her family. Weaved within this narrative is also a story about race. Young African Americans are being shot and no one is really talking about it. Jilly's Aunt is Black and her cousins are too so she fears something could happen to them but no one else in the family want to talk about it. I think the theme of this book is that the best way to understand a topic or situation is to be open to discussing it, as uncomfortable as it may be. Whether she was trying to understand what was going on with race in their area or trying to make sense of the best ways to help her baby sister, Jilly finds that talking about it was the first step -- and learning sign language! This book is fantastic and I highly recommend it, especially for middle school classrooms!! Can't wait for Gino to write another one!
