Hasn't been one that I've found, and I've looked. Finished 'To Snap a Silver Stem' about six months ago, and went down a proper rabbit hole trying to see if the author had any plans. Checked their socials, their publisher's site, Goodreads, the whole bit. The book ends on a pretty definitive note, honestly—the whole arc with the Court of Shattered Branches feels wrapped up. The protagonist's sacrifice seemed pretty final, and the epilogue gave that twenty-years-later closure. It doesn't scream 'sequel hook' to me, more like a standalone with a bittersweet but complete ending.
Sometimes a story is just done, you know? I'd rather have that than a forced continuation that waters down the original's impact. I saw some fan theories about following the side character, Lysander, but they read more like wishful thinking than anything grounded in the text. My advice? Enjoy it for what it is—a fantastic, self-contained dark fantasy—and maybe check out the author's other series, 'The Gilded Cage,' if you're craving a similar vibe.
