The newly expanded book is due out in October, which I think makes it very likely this is the recent mysterious Untitled Star Trek book which has appeared in listings.
If pages and pages of pretty starships in plain old 2D just aren't exciting enough for you, then you'll be pleased to know the new Star Trek Pop-Ups book will be following in November. The book will be written by Star Trek regulars Paula M. Block and Terry J. Erdmann, with pop-up art by Courtney Watson McCarthy. Amazon have now released a cover for this one, which features the TOS movie-era Enterprise. But fear not, the book is set to feature pop-ups from across the franchise, including Borg, Klingons, and Captain Proton!
