Automated recommendation fail

Email this morning from Amazon. "Are you looking for something in our Fiction category? If so, you might be interested in these items." On the basis of my previous purchases, Amazon recommends Scott Lynch's "The Bastards and the Knives", as well as his "The Republic of Thieves". Which would be quite exciting, if it weren't for that fact that neither book is for sale yet. The first one seems to exist only on Amazon, and bears no mention on Scott Lynch's own site; the second I can find no hint of having been written yet, let alone published. Does Amazon need some humans in this loop? Anyone with a passing interest in the fantasy genre could tell them not to spam fans with ads for books that don't exist yet. At least I haven't had an ad for A Dance with Dragons yet, though Amazon UK does claim it'll be published in September this year which is presumably news to the author who hasn't finished writing it...
