I listened to the first episode this morning and really enjoyed it. I liked Playing for Keeps a lot, but I love the Heaven series.
Question for people more tech savvy than I am -- it looks like the book is all up on podiobooks now. Is there a way to drop the whole thing into my itunes? There's no manual button I can find, and it's not showing up in the itunes store, so right now, I'm waiting for each individual episode on a daily basis (which is actually okay, I think. I probably can't listen to much more than one a day).
