David Farland threw a writing contest for stories in his Nightingale universe. Nightingale Songs 1 and 2 represent the winning entries, written by S. James Nelson and Gabriela Martinez, the first set in the future and the second in an Arthurian past. Both are competent stories and both capture their settings well.
Also included in each set is a Farland story. “Mooncalfe” I reviewed here. The other, “Against Eternity,” is an experimental tale written in the second person, future tense. It creates an oddly prophetic tone about a future body in body armor on a future ship thrust into a future war.
