Who is Janet Allegri from The Engines of God and what is their importance?

Janet has been living on Quraqua for three years. She brought few possessions with her at the time, including photos of her brother Joel and his family at Christmas. Janet is reluctant to leave, and she is saddened by the fact that her home will soon be buried under water and mud.

Janet is described as having blue eyes and perfect features, and her demeanor seems almost too socially oriented for archaeological work. She was one of the first people to greet Hutch at Quraqua, and she has worked tirelessly to find the Rosetta Stone that they hope will be there to aid in decrypting the Linear C language. Hutch respects and admires her.
