Henry Neff, author of the Tapestry series, Impyrium, and as of this week, Witchstone.
Awesome writer. Awesome illustrator, and in 2020, he made my year. I DM'd him on Twitter asking if he had a physical copy of his 5th book in the Tapestry series that I could buy, because at that time you could only get it in e-book format. He sent me an inscribed and signed special edition as a Christmas present with a bunch of neat swag. That book is my prized possession.
