William Dietrich's Blood of the Reich will appeal to those who enjoy farfetched conspiracy stories and cartoonish Indiana Jones-style adventure (particularly the tomb-raiding, Nazi-battling kind), but its lack of strong characters and tendency to loose itself in its own topical tangents will likely put off most readers. Indeed, while it certainly requires a fair amount of patience, the book is not the lost cause that many paint it as.
Combining the popular narrative technique of shifting back and forth between time periods, BotR weaves together the interrelated journeys of Kurt Raeder, an ambitious Nazi anthropologist who leads a pre-war SS expedition in 1938 to Tibet in search of an ancient power; of Benjamin Hood, a spoiled anti-Indiana Jones museum curator, sent by the American government to thwart Raeder; and of Rominy Pickett, a modern-day young woman, who finds herself caught up in the legacy of the events of 1938.
To reiterate what many reviewers have said, the overall main character, Rominy, is your average American yuppie. She is sarcastically self-aware but very passive, and more or less just along for the ride. She herself laments this at various points in the book, but even her attempt to take the reins of her own destiny towards the end of the story lacks conviction. Perhaps if the book had continued past the ending (which sets up for a second book that may or may not ever be written), we would have seen more of this evolved Rominy, but no such luck for her character.
As for the other main narration charcters, Kurt Raeder, the sadistic but charismatic leader of the Nazi expedition to Tibet, made for an interesting villain despite his descent into "Wacky Occult Nazi Megalomaniac" territory towards the end. Raeder and his Nazi colleagues find evidence of "Aryan" superiority everywhere, and their self-importance and ardent dedication to their cause is believable and palpable. Raeder's own dogged determination to find a superpower sleeping in Tibet, his self-importance, and his deplorable sadistic streak make him a chilling but compelling character. Meanwhile, Hood is a playboy scholar who has inklings of seeking a life of greater meaning, but despite what he does and uncovers during his adventures, I never felt like he was a particularly compelling character. Like a more innocent version of Raeder, he was rather unlikable in general, but with no interesting aspects to make up for it.
As a whole, though, the supporting characters don't fare well; Jake seems to be a prop for the plot and Rominy's (lack of) character development, going from flat to unbelievably cartoonish after a certain plot revelation. Other incidental characters end up being either caricatures (the mannish aviatrix, the dogged government agent, etc) or just plain uninteresting. Sam MacKenzie was probably the most interesting of all, as a semi-self-assured drifter with a self-deprecating streak whose transformation from tour guide to action hero in the latter half of the book is more convincing than Rominy's entire character arc over the course of the book.
In terms of writing, while the author does paint a few beautiful settings and piques the reader's interest with exquisite details about various locations--from Himmler's medieval "SS Camelot" castle to ancient Tibetan ruins--the author often descends into excessive exposition. The worst of this comes in certain dialogue exchanges, where a characters--usually Jake or Raeder--will explain in detail the workings of, say, subatomic particle physics (yes, really) in the middle of a conversation. Very little of this contributes to the plot or the reader's understanding of it, with even Rominy lampooning Jake and Sam's tendencies to do this multiple times. Thus this book strikes me as a first draft that should have been pared down to perhaps 400 pages. I found myself outright skipping large parts that I knew I would not need to read in order to understand the advancing plot; sure enough, I was able to continue reading without having missed anything. This sort of excess just does not belong in a novel like this.
Overall, the plot advances far too slowly for the first 3/4 of the book, then after the long-awaited and unsatisfactory climax rushes to a conclusion in the end, which leaves me to believe that the book could have been pared down even more to produce a better-paced first half. The story ends with a clear indication that Rominy's adventures are just beginning. But while the adventures of Hood and Raeder in 1938 were fairly compelling, the modern part of the story is contrived and boring; the "ancient mystical power" that Hood and Raeder discover is corny enough without a plot element involving neo-Nazis weaving a grand conspiracy. The author would have been better off weaving a tale of good vs evil that lie solely in the pre-and inter-WW2 era than having the results take place over 60 years later. Alas, Dietrich chose to split the narrative, and result is a book that spends most of its time boring you, drowning out its more interesting aspects with paragraphs of pointless explanations. But for those who are interested in the subject matter, BotR might be worth a look.
