(2018) Mason Burke is a middle schooler with learning disabilities dealing with bullies, grief, and the cop who suspects Mason is responsible for the death of his own best friend. He is also utterly charming. Extra points for (spoiler!) a dog of my favorite literary breed: the Dog-that-survives-the-entire-book-hound. It's a rare breed but (attention authors!) the *best*
Thanks @mandarchy for recommending this one!
