Query: Mostly entertaining

Overall, this was a pretty good book, but it doesn't match Knights of the Kitchen Table and Sam Samurie for Time Warp Trio fun. While it was entertaining to watch them run from the girls, hide from the sabertooth, etc., it was hard to believe that they were in any danger. The dialogue was often witty, but the plot a little thin which took away from the adventure. If you've read the other Time Warp Trio books, then you should read this one, but if you've never enjoyed the adventures of Fred, Sam and Joe you should try one of the better ones first.Also recommended - King Fortis the Brave - probably the best young adult fantasy book to come out since the Chronicles of Narnia were published.
