Secrets of the Sands is book one of five in the Children of the Desert series by Leona R Wisoker.

When Cafad Scratha was a child, someone murdered his entire family. People have questioned his sanity ever since. As the last Scratha, he’s dedicated his life to catching the murderers. Now a desert lord, one of the mysterious elite of the southlands, he stands above every mundane political imperative and rule of courtesy–or so it seems until the king of the northlands tries to bring Scratha to heel. Scratha’s bizarre reaction throws the independent southlands into chaos: he hands temporary control of his family lands over to the king, takes on an assumed name, and sneaks out of the city. The king sends Alyea, a young noblewoman, to hold the ceded prize: but while she understands kingdom politics, she’s quickly out of her depth in the byzantine world of the southlands. What she thought was a quick ticket to power turns out to be a dangerous assignment that may well lead her to a literal dead end. Just as trapped is Idisio, the orphaned street-thief sent by a chance encounter into Scratha’s service. As his new and throughly unstable master goes undercover, Idisio finds himself drawn into the mysterious world of the desert lords and their secrets. Idisio’s growing comprehension of the world he’s stepped into doesn’t just change his beliefs; it leads him to an unsuspected truth about himself that will change his life forever.
