The second book, The Outskirter's Secret was probably my favorite of the series. Rowan's investigations lead her into the Outskirts, where she is forced to rely on Bel and her people for information as well as survival. This arid, inhospitable world is truly fascinating and the nomads that inhabit it even more so. In spite of the hardships, Rowan finds both personal and professional fulfillment here, at least for a while. In the end, she's gained some valuable information, in addition to becoming sadder and wiser.
