Elizabeth Peters: Guardian of the Horizon (USA 2011)

From the Publisher:
From the lost journals of archaeologist Amelia Peabody comes a chronicle from the "missing years" -- a tale of adventure, bravery, and terror.

Readers have long wondered what befell the Emerson clan during the years before the Great War. Now, at last, the silence is broken and the truth revealed of a perilous journey to a secret and mysterious place hidden deep in the heart of the unforgiving desert. An adventure prompted by loyalty to an endangered friend -- and spurred on by lies and treachery -- leads Amelia Peabody and her intrepid family into a nest of vipers lying in wait at a remote mountain fortress. And when a dark past and a shocking mystery are ultimately discovered, a loved one may be lost forever.

From the Publisher:
Ousted from their most recent archaeological dig and banned forever from the Valley of the Kings, the Emersons are spending a quiet summer at home in Kent, England, when a mysterious messenger arrives. Claiming to be the teenage brother of their dear friend Tarek, prince of the mysterious Lost Oasis, the charismatic herald brings troubling news of a strange malady that has struck down Tarek's heir and conveys his brother's urgent need for help only the Emersons can provide.

Driven by loyalty - and a fear that the evil forces opposing Tarek's rule will now exploit the royal heir's grave illness - the family sets off in secret for the land time forgot - a mountain fortress from which they narrowly escaped ten years before. Braving the treacherous desert climate on a trek fraught with danger at every turning, guided only by a crumbling map, the Emersons are unaware that deception is leading them onward into a nest of vipers - where a dreadful fate may await. For young Ramses, forced to keep his growing love for the beautiful Nefret secret, temptation along the way may prove his ultimate undoing. And a dark past and grim obligation have ensnared Nefret once again, as she is helpless to save those she loves most from the prison of the Lost Oasis.
