A review by ponga
Final Days by Gary Gibson

2.0

Too action-oriented and focused on cool visuals for me, especially as the physics feels wrong, and various highly advanced technologies seem to have had minimal impact on Gibson's future society as compared with the present day. (Essentially, it's West vs East with cooler toys.)

Apart from not even handwaving the construction, care and maintenance of exotic matter bridges, and casually tossing off transporting wormhole ends at near-C velocities (the energy budget of that seems about as far advanced from Gibson's portable tokamaks as they would be from coal fires), I got really annoyed with his reversal of which wormhole end permits future directed time travel, and didn't much care for single world determinism as a consequence of closed timelike curves.

But if you're looking for action and don't care too much about the motivations of characters or the internal consistency of the world building, the book might work for you.
