Now, what began as a taunt, a battlefield boast, grows into something more. Something epic. Something romantic. Something that could change the past and the future.

A sharp-tongued folklorist must pair up with her academic rival to solve their mentor's murder in this lush and enthralling sapphic fantasy romance from the New York Times bestselling author of A Far Wilder Magic. Lorelei Kaskel, a folklorist with a quick temper and an even quicker wit, is on an expedition with six eccentric nobles in search of a fabled spring. The magical spring promises untold power, which the king wants to harness to secure his reign of the embattled country of Brunnestaad. Lorelei is determined to use this opportunity to prove herself and make her wildest, most impossible dream come to become a naturalist, able to travel freely to lands she’s only ever read about. The expedition gets off to a harrowing start when its leader—Lorelei’s beloved mentor—is murdered in her quarters aboard their ship. The suspects are her five remaining expedition mates, each with their own motive. The only person Lorelei knows must be innocent is her longtime academic rival, the insufferably gallant and maddeningly beautiful Sylvia von Wolff. Now in charge of the expedition, Lorelei must find the spring before the murderer strikes again—and a coup begins in earnest. But there are other dangers lurking in the forests that rearrange themselves at night, rivers with slumbering dragons waiting beneath the water, and shapeshifting beasts out for blood. As Lorelei and Sylvia grudgingly work together to uncover the truth—and resist their growing feelings for one another—they discover that their professor had secrets of her own. Secrets that make Lorelei question whether justice is worth pursuing, or if this kingdom is worth saving at all.

Magic! Murder! Shipboard romance! Maud Blyth has always longed for adventure. She expected plenty of it when she volunteered to serve as an old lady’s companion on an ocean liner, in order to help her beloved older brother unravel a magical conspiracy that began generations ago. What she didn’t expect was for the old lady in question to turn up dead on the first day of the voyage. Now she has to deal with a dead body, a disrespectful parrot, and the lovely, dangerously outrageous Violet Debenham, who’s also returning home to England. Violet is everything that Maud has been trained to distrust yet can’t help but desire: a magician, an actress, and a magnet for scandal. Surrounded by the open sea and a ship full of suspects, Maud and Violet must first drop the masks that they’ve both learned to wear before they can unmask a murderer and somehow get their hands on a magical object worth killing for—without ending up dead in the water themselves.
