As a child worker of the December Mining Corporation, 18-year-old Jett’s plan has always been to earn a life outside the mines by selling her body—a plan she’s nearly fulfilled until she reluctantly takes on a new trainee from the outside world. The daughter of a government historian, and bartered into the slave trade by her own mother, Fiona is an outsider with a strange wealth of knowledge, and a secret worth dying—and killing—for. While Fiona’s secret may unknowingly bring death and destruction to the December Mines, Jett finds herself letting go of her jaded persona to embrace a friendship that will change her life forever. When she unintentionally becomes the new keeper of Fiona’s secret, Jett is thrust into a fight for survival and a quest for the freedom she’s longed for. Keeping the secret could cost her her life. Searching for answers all but ensures her death.
