I bought this precisely because I read a bad review of it and I figured it couldn't that bad as it's about a girl and a horse. What's not to like? I was right. It's not a bad book, but maybe the reviewer was expecting something a little more adult. This is a book for kids in the younger end of the 8 – 12 age group (depending on their reading age and level of maturity). It's a time-travel story in which the young heroine befriends a horse and together they go back in time and help America in the War of Independence. It's simple and simplistic, not necessarily a bad thing in a book for this age group. It delivers a dollop of easily digestible history, and may be a little didactic at times. It's set up for more stories to follow, but it was published posthumously as sadly the author died in 2013.
