Blackout
This is part one of one of Collis' time travel visits to England during WWII. There's a panoply of grad students missing their rides home and running around in circles and stressing out about deadlines (something bad happens if you run into yourself) I like the familiarity with the setting, but the circular running about and worrying gets a little tiresome. Fortunately it's read by Kathryn Kellgren (she did the Bloody Jack books too) and she's amazing. I'm already into the second part.
