In Bloodlines: Part4, Dr. Hart said
I remember the first time I met Gina. I had just started working for Porter. We flew on his jet to Lake Baikal in Siberia. We drove all day and into the night, until we found this tiny Russian village. A priest there introduced us to this young mother. And then we finally met her two girls. A two-year old named Yevgeny, and her newborn sister, Bronislava.
The path of the August 1, 2008 Total Solar Eclipse through Russia passes through the westmost edge of Mongolia about 800 miles west of Lake Baikal. Was Bree and Gina's home village on this path?
