One of Us Is Lying meets Knives Out —with beasts murder and magic—in this first book in a
thrilling locked-room whodunnit YA fantasy duology by Andrea Hannah and New York Times
bestseller Rebecca Mix. After a decade of war the kingdoms of Avendell and Istellia have
finally agreed to peace. As nobles and magic wielders from both countries arrive at remote
Castle Avendell for a historic all-night masquerade to celebrate King Costis summons an
unlikely group to his chambers: the crown prince his Istellian bride-to-be his personal guard
a wild beast tamer and the palace’s questionable new healer. But before Costis can reveal why
he has gathered them the castle goes dark. When the lights come back the king is
dead—murdered with the princess’s knife in a weak spot only his guard knew of and with venom
from one of the beast tamer’s monsters lacing the blade. With no clear killer—and everyone a
suspect—they make a risky pact: Tell no one until the treaty is signed. But when a winter storm
seals everyone inside and someone aware of the king's untimely death begins to pick off guests
one by one the six suspects must work together to discover who killed the king . . . before
one of them is next.
