There are not a lot of television adaptations that remain true to the books. The Expanse television series is both a great adaptation and a fantastic show on its own. (In fact, it's one of the only shows I'm not allowed to watch before my spouse!)
But this is only true because the books themselves are so good. Leviathan Wakes introduces us to a future that is eerily believable and familiar despite being set all over the solar system. There is a rich variety of characters. And plots and subplots develop and resolve over the course of the series.
If you know someone who is a fan of epic space opera, Leviathan Wakes and the rest of the Expanse books make a great gift.
