I don't know why but I always just keep going back to this book series. I first read this book when I was in high school and I got it assigned to read for my Dutch classes (which was hilarious, cuz we weren't allowed to read translated work, and I found out later that this was originally an English book). It stayed with me long after I left school and I reread it almost once a year. It's just such a great series and I love it so much more every time I reread it.
