In a thrilling new fantasy from the bestselling author of the Storm Siren Trilogy, one girl makes a stand against society and enters a world made exclusively for boys.
Every year for the past fifty-four years, the residents of Pinsbury Port have received a mysterious letter inviting all eligible-aged boys to compete for an esteemed scholarship to the all-male Stemwick University. The poorer residents look to see if their names are on the list. The wealthier look to see how likely their sons are to survive. And Rhen Tellur opens it to see if she can derive which substances the ink and parchment are created from, using her father’s microscope.
