Book Description: Two elite assassins learn precisely how dangerous it is to have something—or someone—worth losing. Ivy Olwen knows how to survive on the streets without two coins to rub together. But when destiny thrusts her into the nest of a covert agency of assassins sworn to drive back the world’s darkness, she acquires a new set of lethal skills. Her education—from explosives to etiquette, sharpshooting to sabotage—is as far-reaching as the organization’s missions. But it’s the hours she spends among the towering bookshelves in the library and stargazing on the roof with Agent Jack Vale that make her heart fly.
