Gullstruck Island is ruled by the Lost, a group of revered oracles whose souls are not permanently connected to their bodies. The Lost send their minds to gather information, track storms, spy on neighbors; meanwhile, their bodies remain behind as empty shells until their minds return.
The Lace people are poor, as well as distrusted and unsupported by any other towns. Their last hope of survival lies in Hathin's sister Arilou, who, with her absent mind and vacant expressions, may be the town's first Lost in generations. They desperately need to believe this, because her existence is the town's only remaining form of revenue. Hathin has been raised with the sole purpose of assisting her sister, of tending to her every need, and of helping to convince the world of Arilou's status as Lost--her body may be empty of all thoughts, but is Arilou really a Lost? Or is she simply feeble-minded? With the alternative too devastating to consider, Hathin sets out to convince the Lost Inspector that her sister is the real deal. And in a world in which souls travel silently and invisibly, one must be careful at all times, especially when dealing with deception.
There are so many twists and turns that I can't say much more of the plot. But I can say that the world created in The Lost Conspiracy is entirely unique and fascinating to no end. The island's politics and prejudice are elaborate, complicated, and real. And the journey Hathin finds herself is exciting because of the many obstacles she faces, but also because of the growth we, the reader, can see in our sweet little friend.
