Scripted Tomes and Tombs - Sara Thomas - Bog

Out in the desert, under the ruins of a city long fallen, lies a secret that will change everything. After days of testing wand candidates, Dwayne's own magic hungers for adventure. So when his master receives an invitation from an arch-rival, Dwayne seizes the chance to do something other than boring experimentation: go to Yumma and assist in an archaeological dig.
Outside the city, all Mei wants to do is explore the forest, but when she has a perilous encounter with a masked figure, she learns that escaping the Empire's borders doesn't mean escaping the Empire. To keep her brother Huan safe, Mei accepts a fortuitous job offer from former client Magdala Gallus: guard the three mages as they travel to Yumma. Frustration. Fear. Opportunity. These lead Dwayne and Mei to Yumma, ruined seat of the Yaniti Civilization and keeper of secrets left dormant for centuries.
