This blog began in 2009, and the posts come to you from the mouths of characters in the books. I've added my own thoughts too, in case you're interested. Cool, huh?! Older posts are a little different but should be equally interesting and helpful in finding good books. Click on the link below for posts about more realistic novels.
This book is the second in the series, and I gave it a rating of four out of five. Dak, Sera, and Riq travel back to ancient Paris where the Vikings are about to attack the city. They see a Viking wearing an SQ insignia, so they assume they're supposed to stop the attack. However, Sera and Riq later decode a message and discover they have things wrong. Dak has mixed emotions between the excitement of seeing history unfold and not getting himself killed. There are battles between the Vikings and Franks, and a little face-off between a Hystorian and the Time Warden.
I wasn't gripped by the beginning of the book. I didn't have any background knowledge about the siege on Paris, so I wasn't real interested. However, the plot grabbed me more as it got into the conflict between characters, and the kids discovered their mistake. I liked Rollo's character along with his giant dog.
