There actually is a US Kindle edition of LABYRINTH at last!
Huge thanks to my editor, Anne Sowards, the e-book group at Penguin/Roc, my agent, for getting it done and to fan Jason Clary for getting me the link. *smooch*
I’m told there are Sony and iBookstore editions too and the Nook and other formats are still being pursued. Thanks for being patient, you guys.
