I do not have a set release date for Survival Instinct, but I do have a cover that was created by Kat Mellon. This was my first time working with Kat, but I'm hoping it won't be my last!
This book has been something I've been working on for quite some time now. I actually started writing The Yearning right after I finished writing Program 13 - which was back in late 2010/early 2011 - so this installment has been a long time coming.
I don't have an actual description for this book just yet, but it takes place shortly after the short stories The Yearning and The Facility (both of which are available now as one eBook). I'll have an official description soon enough. ;)
