From the New York Times–bestselling author: A vampire alliance may turn the Thames blood red in “one of the best vampire novels of the decade” (Booklist).   After a career in her Majesty’s secret service, James Asher’s quiet London retirement was shattered when the immortal, Don Simon Ysidro, solicited his help, ushering James and his physician wife, Lydia, into the vampire underworld. But now it is Lydia who needs Ysidro’s assistance. Her husband is going it alone on the trail of an Austrian spy who is forging a potentially catastrophic alliance with the undead—a secret coalition that has unwittingly lured James into very mortal danger. Lydia can’t let that happen.   She and Ysidro embark on their own pursuit that snakes across the continent from London to Vienna and finally to Constantinople, where an elaborate power struggle between the living and the dead has just begun. It is one that is plunging all of them into the heart of a terrifying conspiracy—with the fate of the entire British Empire at stake.   Following Those Who Hunt the Night, the second book in the James Asher series “captures both the subtle ambiance of turn-of-the-century political intrigue and the even more baroque pathways of the human and the inhuman heart [with] its rich atmosphere and vibrant characters” (Library Journal).   This ebook features an illustrated biography of Barbara Hambly, including rare photos and never-before-seen documents from the author’s personal collection.
