"Once upon a Summer" is a book that is not too serious and not excessively religious. In fact, I think a subtle point was that a person may attend church, but that doesn't mean they are a good person, and that people who do not attend church, may in fact be good people (although I doubt these are the points author Oke was intending to make). I enjoyed the character of Auntie Lou and her valor towards her feelings. I found Grandpa and Uncle Charlie's actions to be awful (concerning finding Lou a suitable husband, and not leaving the choice up to her), and Josh and Gramps' relationship heartwarming. If you're looking for a book to sit back and relax with, then this is the book for you. I recommend.
