Blackout is about a number of characters who travel back in time to view different events during World War II, but after they arrive, there’s a mess up in the time travel lab, and they find themselves unable to return to their future.
This is a fast pace, fascinating insight into the lives of regular people during the war. While Blackout abruptly ends, All Clear continues with the telling of this exciting adventure. I think the publishers found this story too long for one book and made it into two, much to my annoyance when I reached the end of Blackout and discovered the words, to be continued.
Willis is an excellent time travel writer and if you enjoy Blackout and All Clear, you’ll be equally enthralled by Doomsday, but keep in mind, it’s better to read Doomsday first as many of the same characters work at the same time travel lab in all three novels.
