The Atrocity Archives

The first novella, The Atrocity Archive, is a solid 4/5 stars. A delightfully nerdy read, basically H.P. Lovecraft reimagined through the lens of cyberpunk. It's liberally-sprinkled with hacker culture in-jokes but manages to roll a saving throw against getting bogged down in its own cleverness, and the plot has plenty of momentum (and tension! and high stakes! and terrifying extradimensional entities who mean us ill!).

However, the second piece, The Concrete Jungle, is utterly skippable. A big letdown after the first one: it's a dull, repetitious and muddled rehash of the same ideas, except replacing the Lovecraftian horrors with interdepartmental politics. Basically don't bother with it.
