Great Read for 11 Year Old
Format: Hardcover
My 11 year old couldn't put this one down and was a bit sad when it ended. We've already ordered another one in the series.

Page turner that makes it hard to put down. Loved the history and research and the storyline . My 11 year old grandson introduced me to the series and he reads them to me. Gets us closer

The book series that got my son into reading
Format: Hardcover
Very thankful we found this author and these books. This is the first series my son struggles to put down and the mandatory 20 minute reading time with lots of nagging has turned into gentle nudges that he has to stop reading at the next chapter because it is getting late.
