Blackout

A story with a lot of potential is burried under unending descriptions of everyday mundanity and countless repetitions of the same thoughts in the characters' heads (they all seem to share one brain, both in how much they use of it and in the way they all think and behave exactly the same). The time travel setting doesn't actually make any sense, Oxford in 2060 seems to be on the technological level of the early 90s, and the way the characters stumble into their problems is so convoluted that it becomes impossible to keep up suspension of disbelief.
