Allison Alexander is an agent with Interpol.
A young woman in her mid 20s as the series begins, Alexander is a woman of moderate means working as an interpreter for the United Nations. Though hardly rich to her knowledge, she has been able to travel all around Europe, especially the Greek isles, during her teenage years with her mother, an historian and author. And when in the States, she has the ability to take up residence when she desires in a beautiful California coast estate once belonging to a gorgeous movie star who vanished mysteriously three decades before.
Alexander's life is not all idyllic, though. She mourns the loss of her father many year before when he, much like the actress, disappeared overnight. And five years before the series's first adventure, Bart, the man she had always expected to marry suddenly said goodbye and himself vanished from her life. Now in a sudden and surprising turn of events detailed in the first book, both are back and she learns that both are working for the same covert division of Interpol known as Anatasia.
This department with Greek name with the meaning of resurrection (literally "a rising up") is tasked with fighting terrorism in the world regardless of the source or the target. Whether it is Arab extremists or Thai warlords or South American drug kingpins bent on destroying governments to keep their trades alive, the men and women of Anastasia specialize in going deep undercover to burrow into the organizations to destroy them from inside.
Alexander becomes connected with this group through her father, a long standing member, and Bart, the man she loved who disappeared a half decade before. When her father returns, it is a moment of great joy. It is a mixed emotion for her with Bart's return for the question of where he was those years burned deep. Finding he was a prisoner of a Chinese warlord, tortured for months and needing many months to recover helped reduce her anger. His determination to marry her and make up for lost time also helped.
The series describes the many strange and exciting cases and affairs Alexander faces in her life with Bart. Infused throughout the stories, though never at the risk of detracting from the adventure, is the main character's devotion to the Mormon faith, matched by the author's.
