From the comments and e-mails I'm getting, it looks like a lot of people missed the announcement about the next Psy/Changeling book, so here's a roundup of the info I've shared so far.
The book will feature Adria and Riaz. The Arrows will also play a strong role, as will Councilor Kaleb Krychek.
What I haven't shared until now, is that Hawke and Sienna will also have a very strong presence in this book. We're going to see the next step of their relationship, and I think the book will interlink very closely with Kiss of Snow in that sense.
I can't share anything more at this stage - I'll probably talk a little more about the book once I have a completed near-final draft.
Also, I always post release info on the blog and website, but if you'd like to make sure you stay up to date with all the news, here's the link to sign up for my newsletter (please remember to click the confirm link sent to your e-mail after you sign up).
