Mercenary (Little Death Bringer, Book One)

Marin doesn't want to be a lady. She wants to kick butt and take names, but outside forces are working against her.
As if being human, even if she was raised by the King and Queen of the Elves, wasn't bad enough, she's also female. If Marin doesn't train like her life depends on it, she won't be able to hold her own against the elves around her. And at Macon Academy, the weakest link rarely survives.
While Marin wants to be the first female to graduate Macon Academy as a Mercenary, her mother has other plans. The Queen wants her to complete royal training to be groomed for a place amongst Elven royalty.
Between an attempted kidnapping, her impossible feelings for her best friend, and now a fiery magic growing within her, Marin's life is twisting out of control. If she doesn't get a grasp on her problems quickly, she may lose everything she's fought so hard to build.
That's if she can survive at all.
Fans of Sarah J Maas and Kristin Cashore will love this fantastical adventure of danger, loyalty, and unrequited love.
