There has always been a darkness to Ilmar, but never more so than now. The city chafes under the heavy hand of the Palleseen occupation, the choke-hold of its criminal underworld, the boot of its factory owners, the weight of its wretched poor and the burden of its ancient curse. What will be the spark that lights the conflagration? Despite the city's refugees, wanderers, murderers, madmen, fanatics and thieves, the catalyst, as always, will be the Anchorwood–that dark grove of trees, that primeval remnant, that portal, when the moon is full, to strange and distant shores.

Sara Marsala barely knows who she is anymore after the failure of her business and marriage. On top of that, her beloved great-aunt Rosie passes away, leaving Sara bereft with grief. But Aunt Rosie’s death also opens an escape from her life and a window into the past by way of a plane ticket to Sicily, a deed to a possibly valuable plot of land, and a bombshell family secret. Rosie believes Sara’s great-grandmother Serafina, the family matriarch who was left behind while her husband worked in America, didn’t die of illness as family lore has it . . . she was murdered.

In the ancient city of Nineveh, on the bank of the River Tigris, King Ashurbanipal of Mesopotamia, erudite but ruthless, built a great library that would crumble with the end of his reign. From its ruins, however, emerged a poem, the Epic of Gilgamesh, that would infuse the existence of two rivers and bind together three lives. In 1840 London, Arthur is born beside the stinking, sewage-filled River Thames. With an abusive, alcoholic father and a mentally ill mother, Arthur’s only chance of escaping destitution is his brilliant memory.

Dragons are common in the backwater kingdom of Bellemontagne, coming in sizes from mouse-like vermin all the way up to castle-smashing monsters. Gaius Aurelius Constantine Heliogabalus Thrax (who would much rather people call him Robert) has recently inherited his deceased dad’s job as a dragon catcher/exterminator, a career he detests with all his heart in part because he likes dragons, feeling a kinship with them, but mainly because his dream has always been the impossible one of transcending his humble origin to someday become a prince’s valet.

When Lauren returns home to her flat in London late one night, she is greeted at the door by her husband, Michael. There’s only one problem—she’s not married. She’s never seen this man before in her life. But according to her friends, her much-improved decor, and the photos on her phone, they’ve been together for years.
