I'd suggest any writers/authors/people interested in craft read Rebecca LuElla Miller's entry on pacing as it pertains to this book. And J.L. Mbewe has links to several interviews. (Is anyone else surprised that such a bubbly author wrote Nym?)
That's about all I have, though I was rather surprised that of the CSFF bloggers I read, I seemed to see the most Christian content here. Maybe that's because I have some familiarity with To Write Love on Her Arms, a movement with a lot of Christian links. From their "Learn" page:
You were created to love and be loved.
People need other people.
Your story is important.
Better days are ahead.
Hope and help are real.
You are not alone, and this is not the end of your story.
In Storm Siren, God is only vaguely referenced and Christ doesn't seem present at all, so for me the message of hope rang a touch hollow. On the other hand, many people are in a place where they don't think God cares or they can't believe in Jesus. Those kind of people might be moved by the rather modest proposal that the protagonist, who feels like a monster, is deserving of love, and might have actually been created for a purpose. But a more explicitly Christian story might lose those same people, and maybe the later books will build on that modest foundation to help some broken people look into finding lasting hope...
One last link to the other bloggers, if you missed anyone.
