I would like to thank JB Bell, Sam Jones, and Andan Lauber for their help in inventing Jayné Heller and for handing me Guilty Pleasures back during the heyday of the Abbey. I would also like to thank Jayné Franck for lending her name. I owe debts of service and gratitude to the members of the Santa Fe Critical Mass group, including S. M. and Jan Stirling, Emily Mah, Ian Tregillis, Melinda Snodgrass, Terry England, Walter Jon Williams, Sage Walker, Vic Milan, and the auxiliary presences of Carrie Vaughn and Diana Rowland. The book would not exist without the faith and hard work of my agents, Shawna McCarthy and Danny Baror, and my editor, Jennifer Heddle. The strength of the book is very much an honor to them. Any errors are entirely my own.
