There are three full novels (The Wild Hunt, The Wild Curse and the Wild Herald), plus two short stories and a novella (Faerie Nights, Faerie Oaths and Faerie Hearts). That makes six total, although only four are up for sale (the full novels plus Faerie Hearts). If you want the two extras, you can get them for free if you sign up to my newsletter. You can do that following this link.
The Faerie Sworn series is complete.
Maybe. I've learned never to say "No way!" but if I do revisit the world, it'll be a new story. Meaning? Troy and Lily might make an appearance, but they won't be the main characters.
I've been toying with the idea of a Marast-centric story where we get to see how he became the Unseelie Hunter.
I've also been thinking of coding a little game (text-only, make your own choices type) to have some extra fun with courtly intrigues.
None of those ideas are plans for the moment. We'll see.
I would love to! I'm a huge fan of audio, and nothing would please me more than listening to my characters.
However, at this point, it's not something I can do independently. I'm an international author who can't take advantage of Amazon's ACX service, which is a bummer.
A company picking up the audio rights to any of my series and making it happen, though? That's on the table. The bigger the success of the other formats of the books, the better leverage I'd have to make it happen.
Bottom line: become a book-pusher!
