Snowflake Kisses (Jordon Greene, Yayira Dzamesi) is a super cute short story in comic format, which is related to a book I haven't read but was pretty intelligible without it. Skylar and Jacob are dating, and go with Skylar's parents to have a little Christmas holiday together. 

Skylar's frequently non-verbal and likes to wear skirts, and Jacob is just helplessly in love with him, it's really cute. The art works well and is really clear, and I liked that the speech bubbles are different shapes to show Skylar's different ways of communicating: mouthing words, using his phone to speak for him, or using ASL.

It's sweet, and probably more meaningful for people who've read the book, but still fun for me.
