Struck introduced readers to Laney and Leela, twins who, except for a birthmark, are identical. When the people from their small town disappeared, they traveled to a different dimension—Antonia—to save their friends and family from slavery. Antonia strives to be a perfect society, but beneath the surface, there’s an underground resistance, rumors of a sickness spreading among the people, and a king who is trying to maintain the chaos by breaking an ancient curse. To complete the mission, Leela traded herself for her family’s lives, promising to marry the Antonian king in order to break the curse that is killing the Antonian people. The Mark and the Match follows the twins as Laney tries to return to Antonia to save her sister and as Leela prepares to marry a man she doesn’t even know. Danger is never far from either of them, and they soon learn that safety is an illusion.
