There seems to have been a small hiccup in the mass-market trade paperback release of The Fallen Queen, scheduled for May 15, and the new edition is not yet available. As a result, some of the pre-order links have stopped working (or have disappeared entirely), while others are still indicating that pre-orders can be taken.
My publisher is currently trying to sort this out with the distributor, but we expect the book to be available by June 1 at the latest. My virtual book release tour, originally scheduled to begin this week, will resume once the distribution has been sorted. My sincere apologies to anyone who pre-ordered the book and was expecting it to be delivered yesterday, as well as to the bloggers whose schedules have been or may be inconvenienced by the rescheduling.
As a small consolation, if you're still awaiting your book, drop me an email with your mailing address and I'll send you a signed Fallen Queen bookmark.
