A devastatingly romantic speculative novel about two time travel agents who meet - and fall in love - out of order, racing toward an ending they already know can’t be changed.

Emilia is a loyal employee of the Directory, a shadow organization that governs time travel to ensure the integrity of the world’s timeline. When a fellow agent, code name Ariel, tries to kill Emilia for a crime she hasn’t yet committed, she gets pulled into a game of cat and mouse that spans centuries, where past and future blur. Everything they do has already happened, but their current selves are unaware of what’s to come. And if they step out of line, the timeline could collapse, and they themselves could wink out of existence.

Sent to a major timeline event when the President is assassinated, Emilia must ensure that the assassination occurs the way she remembers it. The assassination doesn’t go exactly according to plan, but with only slight aberrations, the timeline remains intact. Flustered after the partially successful mission, Emilia flees and runs into Ariel once again. This time she takes no chances and kills him…despite the fact he doesn't fight back.

But death doesn’t mean much to time travelers, and Emilia runs into Ariel again and again. This Ariel doesn’t contain the anger he once did, and Emilia can’t help but fall for him, all the while knowing she is his murderer, and their time is running out. Only by working together - with a little help from their younger selves - could they potentially change the fate of humanity.
