To the OP, thanks for the code. My son has read the first one and wants the other two. I think the "Easter Bunny" is bringing # 2 for him. I will offer to let him read my Kobo but he told me before that he doesn't think he would like reading a ebook. I must say, I like it because I have lots of books at my disposal without going to buy one at the store, since I live in the country but I do love the smell and feel of a real book.
I got all three of them for $4.21. I'm happy with that.
