Acclaimed crime writer Elizabeth Hand returns to her "fiercely frightening yet hauntingly beautiful" cult-favorite series: Photographer Cass Neary is hard-up for cash and in more danger than she realizes on the hunt for an ancient, legendary book (Tess Gerritsen).

Photographer Cass Neary is desperate to get home, and she's already lost her camera - like losing a limb. Now her only chance is to cash in on a deal that a friend is about to cut for a legendary illuminated manuscript: The Book of Lamps and Banners. Rumored to have been rescued from the Library at Alexandria, the Book is said to contain ancient esoteric knowledge, even an otherworldly power.

So when an intruder brazenly steals the manuscript, Cass and her ex-con lover, Quinn, must get it back - plunging headlong into a shady underworld where antiquarian booksellers, unhinged tech entrepreneurs, and brutal nationalists all converge. This breathless psychological thriller, featuring one of the greatest amateur sleuths of the past decade, could only come from the mind of Elizabeth Hand.
