My Supplies Made Her a Queen!

Ewan Lynn and General Shawna Quinn know each other only through a battered Bronze Coffer. It belonged to Ewan's grandmother, and he found it after the Lynn family threw him out. Anything he puts inside arrives in another time, at the frontier pass where Shawna is holding on with what is left of her army. Her soldiers are cold and short of food. Barbarians press the pass from outside, and the Imperial Court has left her there without support. Ewan sends clothing, medicine, food, weapons and machines through the box. Shawna comes to believe the sender is the Divine One. The help from a distance turns into a rescue that puts lives on the line. The ruined city behind the pass starts to come back. They also begin moving against the Imperial Court. The barrier between their two times, which until then only the box could cross, comes down.
