This was the second book of Willis’s two-parter that began with Blackout. Unfortunately I did not know this when I started Blackout and so I got to the end of it and then realized the story would be wrapped up in a second book, a second book that was only held by three libraries in Vermont. I am a bit of a pill about buying new books, I just don’t do it, so I was immensely grateful when a friend gave me an advanced reader copy of this book. It was terrific. It actually resolved without killing off too many main characters. I enjoyed the story. Willis’s theme of missed messages makes a lot of this book -- the main plotline of which involves time travelers from 2060 going back to the Blitz and getting a little stuck there -- really tensemaking. Sometimes almost too much so. Every time chatacters walked past each other or just missed eachother I was reading it going AAAAAAAAGGGGHHH. So I guess htis means it was well-written and I love Willis’s writing generally, but I find the ongoing tension in this pair of books somewhat tough to deal with. So well written, so much great historical information, but a little nail-bitey for my tastes.
