This message currently appears for this book here at Amazon:
"Item Under Review
While this item is available from other marketplace sellers on this page, it is not currently offered by Amazon.com because customers have told us there may be something wrong with our inventory of the item, the way we are shipping it, or the way it's described here. (Thanks for the tip!)
We're working to fix the problem as quickly as possible."
Does anyone have any info on what specifically is wrong with the book? I've read a couple of reviews here that mention some pages missing or duplicate stories or something like that. It looks like there's a problem with books 1 and 2. The others in the series are still being sold by both Amazon and independent sellers. If anyone has any additional info on this please post it here, thanks.
