Arla Vaughn: Pre-Columbian Treasure Series – the Inca.
 
While traveling on a local bus in Chinchero, Peru, Arla is approached by a mysterious female peddler who shows her a small, silver warrior.  The statue is identical to those found only in rare Inca tombs located high in the Andes. Arla suspects this is a genuine artifact, perhaps stolen from the same Capacocha burial site her co-worker, Lance Hayden, is seeking.  When the woman tells her she has many more items for sale, Arla follows her to an abandoned house. Too late, Arla realizes she has fallen into a trap! 
 
Arla gets kidnapped by a group of ruthless thieves who are holding Lance Hayden hostage. They believe Arla’s in possession of a journal, which is the final link to the Lost City and the secret it holds… 
 
Death lurks, biding its time… This is a race against time that takes Arla to a snowy mountain peak and a clash with the looters for the most priceless treasure of all – the golden condor!
 
The second book in the series begun with The Mayan Mask of Death.
