I read this series when I was in grade nine, and loved them so much... now, when I re-read them, they're still good but clearly for younger teenagers. I finished the book in little more than an hour.I like the concept of it: dead girl in heaven, sent to go back in time to be an angel in all those historical events we know of... it's charming, really.I recommend this series for budding readers (young girls in the ages between 10-15) who are looking for a good story with a relatable main character.
