A pretty good story. He has definitely done his research. Even though the time travel part is a bit of junk science (which he admits in the afterword) it sounds convincing enough. He took some weird quantum theories and made some huge extrapolations to get time travel to work. The medieval setting was the best part, which is what the story really was about.

His writing was a touch amateurish at times, and the characters were not that interesting. The big Dutch guy (forget his name) ended up being Mr. Medieval and jousting and swordfighting and the whole nine yards. That seemed too convenient for me.

Anyway it was worth a read just for the medieval parts. I read it as an audiobook. I think I'll get Prey next.
