Gripping horror undermined by a hasty conclusion
"Metro 2033", a dark sci-fi novel written by Russian author Dmitry Glukhovsky, was a great thrift store pickup. It is a read that, right up until the very end, managed to entertain me thoroughly.
The book explores a living and organic world, where the ravenous underground indiscriminately swallows up the inhabitants seeking survival. The protagonist, Artyom, will have to face countless obstacles and dangers caused not only by monsters, but also by people themselves.

Another interesting aspect is the author's ability to build a detailed map of the underground, allowing the reader to navigate this complex system of tunnels. This style of worldbuilding vaguely recalls J.R.R. Tolkien's "The Lord of the Rings".
The fatal flaw of the work is its inability to tie up loose ends comprehensively: in the ending, in fact, the author barely explains what these new dark beings threatening the subway stations actually are.
Even though the drop in quality at the end is evident, it remains a read that I highly recommend to fans of dystopian horror.
