NATIONAL BESTSELLER • From the bestselling author of The Night Circus, a timeless love story set in a secret underground world—a place of pirates, painters, lovers, liars, and ships that sail upon a starless sea. Zachary Ezra Rawlins is a graduate student in Vermont when he discovers a mysterious book hidden in the stacks. As he turns the pages, entranced by tales of lovelorn prisoners, key collectors, and nameless acolytes, he reads something strange: a story from his own childhood. Bewildered by this inexplicable book and desperate to make sense of how his own life came to be recorded, Zachary uncovers a series of clues—a bee, a key, and a sword—that lead him to a masquerade party in New York, to a secret club, and through a doorway to an ancient library hidden far below the surface of the earth. What Zachary finds in this curious place is more than just a buried home for books and their guardians—it is a place of lost cities and seas, lovers who pass notes under doors and across time, and of stories whispered by the dead. Zachary learns of those who have sacrificed much to protect this realm, relinquishing their sight and their tongues to preserve this archive, and also of those who are intent on its destruction. Together with Mirabel, a fierce, pink-haired protector of the place, and Dorian, a handsome, barefoot man with shifting alliances, Zachary travels the twisting tunnels, darkened stairwells, crowded ballrooms, and sweetly soaked shores of this magical world, discovering his purpose—in both the mysterious book and in his own life.

When a sorceress is captured by the king's guards for her complicity in crimes against the kingdom, she finds herself falling for the mysterious human doctor she's been charged to work with while they try to solve a string of murders. Illyse prefers to isolate herself from the age-old conflict between her coven and the humans of Sjökanten, but not at the expense of her own life. Captured by the king's men, she is threatened with the ultimate demise for sorceresses-being forever imprisoned in ore-unless she manages to put an end to the gruesome murders of human citizens at the hands of a mysterious sea creature. Bound by an iron band that limits her power, Illyse, and her fox familiar, join with Garit Darling, a medical practitioner and an enigma unto himself. Together, they delve deep into forgotten lore and forbidden romantic entanglements, despite a ban on relationships between sorceresses and humans. However, when it is discovered that Garit's past is more closely tied to their investigation than either initially realizes, soon their passion and distraction from the crimes may just be at the cost of Illyse's potential freedom... and Garit's life.

Betrothed by her father to Jarrett Chandler before she was even born, Laura is unwilling to be a helpless pawn.

But even she admits that the tingling which courses through her body as he takes her into his arms is not fueled by fear--and she succumbs to her powerful longings.

Earth is a dead cinder and the last of the human race struggles for survival beneath the dense clouds of Venus. Two courageous visionaries--the fighting men Brainard and Gordon--must struggle through the hellish surface jungles, but if they fail, both Venus and Mankind will die.

Nere has never understood why she feels so much more comfortable and confident in water than on land, but everything falls into place when Nere learns that she is one of a group of kids who --unbeknownst to them -- have been genetically altered to survive in the ocean. These products of "The Neptune Project" will be able to build a better future under the sea, safe from the barren country's famine, wars, and harsh laws. But there are some very big problems: no one asked Nere if she wanted to be a science experiment, the other Neptune kids aren't exactly the friendliest bunch, and in order to reach the safe haven of the Neptune colony, Nere and her fellow mutates must swim through hundreds of miles of dangerous waters, relying only on their wits, dolphins, and each other to evade terrifying undersea creatures and a government that will stop at nothing to capture the Neptune kids . . . dead or alive. Fierce battles and daring escapes abound as Nere and her friends race to safety in this action-packed aquatic adventure.
