Its a great book series! The one problem is..... Well, the first book, its a great book, I understand it perfectly, the second book, the first half was like the first book, not complex and easy to understand. Then, the second half got really complex and I got lost. The third book..... I got lost really quickly, at some points I didn't even know what their goal was! But I'm not saying that Orson Scott Card is a bad writer, i'm saying that the concepts, like everything with time, traveling back and fourth, changing everything, etc Its really complex for me. I'm not an adult, so maybe my brain just hasn't grown enough for me to understand. But either way, it was a great series!
