This book is like nothing I've ever read before. It is a story about a story within another story. Really. In the guise of the story within the book you hold and read "Ship of Theseus" is another story contained within, a trove of secret coded messages between the book's author and the book's editor/translator. Then, as if that is not exciting enough, there is a conglomeration of notes, letters, postcards, etc. between the two readers of the book, Jen and Eric, as they work through the novel and try to figure out all of the pieces. A completely original, engrossing, and enthralling read.
