Flower of Steel Vol. 1 (novel) - Flower of Steel, #1

Tossed to the side. Yearning for stability. Rediscovering true love. Marina von Harrant tasted the sweetness of first love as a child at the Imperial Palace, playing chess with a teary-eyed boy. As the years passed, that golden afternoon became a faint yet precious memory. When her engagement ends in betrayal at the age of eighteen, Marina pursues her dream job: she becomes a government official and returns to the Imperial Palace.
Hopeful about meeting her sweetheart again, she instead finds herself buried under piles of grueling work. Despite that, her first love soon resurfaces, but not in the way she expected. Now, Marina is caught in a complicated love affair with three men within the Imperial Palace: the arrogant Crown Prince, the flirtatious Senior Secretary, and the amiable Royal Knight. With work up to her neck and three men occupying her thoughts, will Marina be able to become a legendary bureaucrat and find her lost love? She'll have to navigate ups and downs, and soldier through twists and turns, in pursuit of her slice of happiness. When the world's against you, it takes nerves of steel to fight back.
