I have already snarked about the quality of the prose of this book; apart from that fairly major consideration, my only other objection is that it doesn’t really deliver on the Miltonian reference of the title other than by having a major character called Angelchrist. The story is a workmanlike time travel tale with alien incursions, split between a rather vague future London and a more precise 1910 setting. In the audio version, Nicholas Briggs does a fantastic job of injecting life into Mann’s prose (though I find his Eleventh Doctor too demotic). All but completists can skip the dead tree version, the audio is a bit better.
