...they just don't exist anymore on Amazon.com:
In brief: Books published by the Macmillan group, which include all of mine, Uzee's Trespassing (pub'd by Picador) and many others (Hilary Mantel, Ishmael Beah, Janet Evanovich) have been removed by Amazon because of a disagreement over pricing of e-books. Amazon, which sells e-book downloads for its Kindle reader, prices everything at $9.99, which doesn't leave much to go to the publisher and author after Amazon takes its cut. (Typically, I make between 75 cents and one dollar per new book sold; if a new book is ten bucks, I'll get 50-75 cents per copy. Publishers will also receive less, which leaves them less cash to pay writers for their books. Amazon will net less also, but will be spending less on warehousing, shipping, paying staff to pull the book and pack it, etc).
Publishers have been pressing Amazon to raise prices to around $15, which would be more in line with a new book price after Amazon takes its usual huge discount (which us writers also pay for, by the way). Amazon has been refusing; meanwhile Macmillan has offered its list to Apple, which is launching its own e-reader and has agreed to a pricing formula more in line with what Macmillan wants.
So in retaliation, Amazon has pulled our books. Thanks, guys! This is why I hate business, pretty much.
I can't tell people where to buy their e-books, so I won't; but I will say that if you're shopping for something of mine, or for Uzee's Trespassing or anything else that's suddenly vanished from Amazon, you can still find it all at barnesandnoble.com, borders.com, or--maybe best of all--through an order at your local independent book store, the one run by the nice old lady and/or the cynical bearded guy and/or the weird grad students with all the piercings. Hey, stop in and say hi, they'll appreciate the business...
