There is many different types of science-fiction read, this one is not one of alien monster and big giant spaceship so if you’re looking for that, you might pass. In fact, I hardly even consider it a science-fiction book, being so close to reality and having very few elements of what, for me, makes science-fiction what it is. That being said, this is a well build book!
First of all, this is tenth book of the Enigma Series, which I never read any before, I don’t know how much link there’re between each of them, but for the storyline, I wasn’t out of place and could easily follow it, but I find that the characters were a bit generic, not unique and mostly interchangeable, maybe that’s a point I would reconsider reading the previous one, but for this particularly book, I think that the development of characters is probably the lowest element of all. That being said, this book bring you in a very political-economical complex intrigue, with some technological elements (that’s is why I wasn’t sure it really belong in science-fiction…), but the story is very well put into place, like I said, complex, lot of characters, many different settings and time, an intrigue that play on an international level, etc. but the authors find a way to keep it going on track for the entire book and that’s good work. The writing was good but I would say a bit dry (in French we call it «une écriture sèche») not sure is dry is appropriate in English, but I mean a writing that is more factual then poetic, not a bad or a good point, can be both, it depends on your personal preferences! So, not a big win for me (personal taste) because of all this economical part of it, but if you love complex intrigue, have an interest in economy and crypto-currency (which by the way is very original, we don’t see much book on that subject), this might be a good pick!
