FROM THE SEPTEMBER ISSUE

NO WINNER: We asked you to suggest a happy ending to a thriller about some terrorists with a bomb and a U.S. president who faces a choice of two kinds of hypersonic weapons to end the threat. We were looking for a response that would probe the trade-offs between air breathing and boost-glide weapons, and suggest a plausible ending. We didn’t receive an answer that met that requirement, so unfortunately our notional novel will have to go unfinished.
