Once there, she discovers that her family is bound up with the Ministry of Maps, a mysterious agency who maintain the borders between this world and the Uncharted.

With the help of Mila Wendell, a traveller on the canals, Sienna discovers her own magical ability and a terrifying place of blood that awaits in the world beyond.
