A midnight adventure into the Forbidden Forest changes everything when Mattheo Riddle is bitten by a werewolf. As his best friend, you’re determined to help him survive the curse, one disastrous full moon at a time. But when an ancient magical mate bond forms during his first transformation, friendship becomes a lot more complicated—and Hogwarts is about to discover that keeping one grumpy werewolf under control is far easier than keeping his feelings hidden. Or, in other words: one cursed Slytherin, one stubborn best friend, several chaotic full moons, and absolutely no one is having a normal seventh year.
