In today's Guide to the Hellfire Gala preview it featured upcoming titles at the books end and there was an untitled title amoung them with its title blacked out with a classified shielding.
To me the title reads "The Trial", which leads to speculation on who the trial is for ?.
The obvious candidate would be Wanda Maximoff the Scarlet Witch, others that spring to mind are Henry McCoy the Beast and possibly Raven Darkholme Mystique.20210429_183707.jpg
