Book(s) spotlight: Keepers Trilogy by David Dalglish
I want to preface this by saying I may be a bit biased here. If you saw my post about planning this, I mentioned befriending an author on Twitter, getting to read some of his books before they were published, and getting to play test his choose your own adventure game for a series.
That's David. Keepers was the first series of his I read, and I fell in love. It's high fantasy with a wonderful Ensemble cast, LGBT rep, handling of trauma in ways that made me thank him.
Finishing book 2 was really the start of our friendship, because I reached out to ask him if I could homebrew one of his monstrous races for D&D. He said yes.
One of the things I really loved about Keepers was that the main character is A HERO in his own right, but he's still humble, down to earth, makes mistakes, and ultimately a vehicle for the true hero to come forth and do what needs to be done.
From beginning to end, I was enchanted, and I can't wait to see the final product of his choose your own adventure - because yes, it's for this series (and, he's implementing nonbinary options for the MC of the story).
