War of the God Queen by David Hambling

SPFBO6

Thrown back through time… Jessica has only her wits. Will she find a way to survive long enough to get back home? She was fresh out of architecture school and ready to take the world by storm. She wasn’t prepared for what came next. An alien encounter that sent her falling through a portal into another world Jessica’s plight looks hopeless -- she doesn't understand the language, the bronze-age culture, or even how to defend herself. She’s not a Connecticut Yankee and this is definitely not King Arthur’s court. The locals are unimpressed. What’s her next move? Her only goal is to get back home, but Jessica has landed in the middle of something sinister: in the ancient near east, circa 1000 B.C., a war rages. Can she stop an alien invasion through time? She’ll need help, but who can she count on? You’ll love this brilliant take on portal fiction, with twists and turns that are different than what you’ve grown to expect.
