His Hollow Kingdom

Wren Adesanya bakes for the dead. It doesn't pay well, but it pays, and the bridge over her night bakery keeps the living out. Then a prince walks in at three in the morning, orders a loaf he can't eat, and tries to buy her silence with a kingdom she's never heard of. Idris has been dead four hundred years and his Hollow Court is starving. The city above has been quietly eating it — through Wren's family, one funeral at a time. Now the bishops want a sacrifice, the mortal authorities want the bridge cleared, and Wren's own blood is the seal everyone has been looking for. She won't give up the bakery. She won't give up Idris. So she's going to open a door that shouldn't exist and feed both cities from the same oven.
