I second (third, fourth, whatever) all the nominations here. One of Female Hawk's stories that Blind Passenger mentioned is
Trusting Me, Trusting You and it's a real rip-snorter. Clark has been imprisoned by Bureau 39 for years and Lois is charged with securing him. Their lengthy journeys to trusting each other - not to mention loving each other - are both poignant and painful. It's a long read, but one for which you will reap some real rewards.
I miss her on the boards. Her work was always -
always - top of the line.
I hope you enjoy all of these tales.
