The brilliance of stars / J'nell Ciesielski.

Washington DC, 1914. Ivy Olwen knows how to survive on the streets without two coins to rub together. But when she finds herself whisked into a secret society that seeks to maintain the balance of good and evil in the world, she can't believe there's more to life than just surviving. In the hallowed and historied halls of Talon, she learns European languages and ballroom dancing, as well as demolitions and sharpshooting - in short, everything a spy and assassin will need to survive in the field. The first day Jack Vale meets Ivy, he knows she is not to be underestimated. The second day, he knows his heart will belong to no one else. Between sparring bouts and constellation gazing, Jack takes Ivy under his wing, and the two form a bond that soon turns to love. While the rest of the world tumbles into war, the two embark on an official mission to take down a madman who has left a trail of blood and murder across Russia. Little do they know the unfathomable peril waiting in the wings of a chaotic Europe.
