This is the fourth, and maybe favored book in the Theodosia Thockmorten series.  The setting is Egypt, where Theodosia, a strong, witty girl, discovers more about her birth and history…and how she is connected to the fight between the Brotherhood and the Serpent of Battle.  Filled with mystery, adventure, twists, and turns, periodic comic relief is welcomed, in order to give your nerves a break from the races against time, encounters with evil people and dark, dark magic.  Young and old, alike, would enjoy this romp of a tale.
