Wren is a thirty-year-old book editor who has started to find the distance between who she is and who she thought she would be by now harder to ignore. Her relief comes from gaming and from two online friends — Kanaria and Lonan — who she occasionally plays with and chats to across the internet. When Kanaria suggests they finally meet in person at a local game convention called GameCon on May 31st, Wren agrees. A terrible accident happens at the venue that day. Wren panics. Then everything resets. It is May 31st again. She went back in time, and now she has to figure out what to do with that.
