The First Bright Thing by J.R. Dawson

If you knew how dark tomorrow would be, what would you do with today?

"This is the magic circus book that I have been looking for all my life."—Seanan McGuire, New York Times bestselling author of Every Heart A Doorway.

Ringmaster — Rin, to those who know her best — can jump to different moments in time as easily as her wife, Odette, soars from bar to bar on the trapeze. And the circus they lead is a rare home and safe haven for magical misfits and outcasts, known as Sparks.

With the world still reeling from World War I, Rin and her troupe — the Circus of the Fantasticals — travel the midwest, offering a single night of enchantment and respite to all who step into their Big Top.

But threats come at Rin from all sides. The future holds an impending war that the Sparks can see barrelling toward their show and everyone in it. And Rin's past creeps closer every day, a malevolent shadow she can’t fully escape.

It takes the form of another circus, with tents as black as midnight and a ringmaster who rules over his troupe with a dangerous power. Rin's circus has something he wants, and he won't stop until it's his.
