Bests & Worsts Reviews from Amazon

I lose a bit of confidence in a work of history when an event stated as fact is wrong even though it may be of minor interest in a history of the US. On page 32 is this: "James was born in 1566; the next year, when his mother died, he became king of Scotland". His mother, Mary Queen of Scots, did not die in 1567. Mary was executed by Elizabeth I in 1587.
