All Clear, by Connie Willis
Well, maybe not quite clear, at least sometimes. This second part of the time travel story that begins with Blackout involves a dizzying array of contingencies.
Of course, my occasional moments of confusion may be related to the fact that I listened to the two cds in reverse order. Unintentionally, of course.
Anyway, I thoroughly enjoyed this tale and was sad to finally say farewell to Polly, Eileen, Stephen, Paige and others. I was also pleased to be reunited with a character who kept a promise, and to discover that an aging man had more allies and less to worry about than he, and the reader, had thought.
And I learned a lot more details about the war, especially the Blitz. I especially enjoyed the bits about the code-breaking centre of Bletchley Park, as part of my novel under construction is set there.
