However, the good thing about the book is that it apparently puts the VMs within the context of early modern astronomy, which - given the whole of the astro section and the sun/moon symmetries, which are especially apparent once you've fixed up the page order in Quire 9 - has to be a real possibility. Also, there seems to be a lot going on, which is normally a good thing in novels. :-)
Here's the publisher's (Flash-heavy) page on the book: there's a nice little quiz to do there, if your Spanish and knowledge of astrophysics are up for some fun (I kid you not). Here's a YouTube interview with the author; his UK literary agent's pitch for the book; and a 5-page Spanish PDF from the original publisher's site (though it only recites late-16th century astronomical history, don't struggle through it looking for any insight on the VMs on my account).
I don't know: it all sounds a lot like Enrique Jovan has had to labour long and hard to bring the reader up to scratch on the VMs (which probably accounts for the high page count) within its presumed historical context (I'm guessing the author has plumped for 16th century, but I could be wrong). Perhaps that prolix mix - of journalism and plot - is the novelistic curse of the Voynich from which novelists have to engineer an escape, lest the reader gets trapped with them? :-o
