The John Wick comic can be canon, but it often depends on how it integrates with the main storylines and the official pronouncements from the franchise's creators. Sometimes, supplementary materials like comics might have a slightly different status within the overall canon framework.
J John went to a magic show. He was so eager to be part of the act that when the magician asked for a volunteer, he ran onto the stage. But instead of following the magician's instructions, he did his own 'tricks' which were just really silly moves, making the whole audience burst into laughter.
Well, one J John funny story could be that J John once tried to bake a cake but ended up using salt instead of sugar. The look on everyone's face when they took a bite was priceless.
The novel could be about a lot of things. It might focus on characters dealing with personal challenges in a specific setting. Or it could be a tale of adventure and discovery. Without more details, it's difficult to pin down exactly.
I'm not entirely sure specifically as there could be various aspects to it. It might be about John Boyega's experiences related to the new Star Wars canon books, perhaps his influence on the stories, or his own journey within the Star Wars universe as it's presented in the new canon books.
His story might stand out because of his unique character. John Boyega brought a certain energy to the Star Wars movies, and that could translate into something special in the books too.
