Based on this information, I cannot consider myself a Hugo winner and will not be citing the 2023 award result in my biographical details, or on this site.
What’s his work like? Reading some of the descriptions on his site it sounds like it has some horror elements.
Definitely a lot of horror elements in the few I’ve read (Children of Time + sequels, Cage of Souls). I’ve only just scratched the surface, the man is a writing machine, but it does seem to be a trend so far.
He blends genres a lot and even his own work is kind of eclectic and all over the place, but his worldbuilding and the ability to take a totally alien concept and make it utterly believable are just top notch.
