A Wife for the Last Monster
Tessa Ward breaks supernatural marriage contracts for a living. When her sister vanishes into a fortress of the city's oldest families, she has three nights to get her back, and only one way through the door: marry the creature who owns every debt in Oakhaven. Adrian Voss is courteous, feared, and behind disappearances Tessa has investigated herself. His one condition: while she wears his ring, she must never ask him to forgive her.
