Yes. He left an unfinished manuscript that was cleaned up and finished by another author (a very mysterious and humble one at that). The third book is Survivors and will be released May 22, 2012. Survivors (The Morningstar Strain) is the link to it. I've already pre-ordered. I'm very much looking forward to the release as I followed the thread of the man who was ghost writing. I have to say that the world lost a great author in Zach. He was writing at this level while still in his early 20s. I was lucky enough to contact him and get him to autograph a couple of books. One was for my mom who to this day counts that book as the best birthday gift to date. I sent him a fan letter to him with the books and he said it was his first fan letter and he posted it in his office. We emailed back and forth and i still have those emails. I cried like I lost a friend when he died. I really feel like I did.
