Description and Title for My First Novel

I've been trying to write a "back cover summary" description for my first novel to use when friends ask, "what's it about?"

Here's my attempt:

Rica grew up at a strict military school in an isolated village. She's been trained to obey orders without hesitation and knows little of the world beyond the school except what she's been taught. Her teacher doesn't believe she has what it takes to become an officer, so she's about to start her life as a mercenary when a heavenly being appears. He indicates that she's the new queen of the kingdom of Norida by decree of the kingdom's god.

Norida's high ministers have ruled for twelve years, since the death of the last king. Rica tries to learn her new duties and what powers she holds as Queen, but her High Ministers are more interested in manipulating her into doing as they wish than in educating or obeying her. But she's too stubborn to let that stop her.

When two assassins attack her, Rica realizes that her ministers and perhaps her own guards want her dead. Now she has to discover who her enemies are and bring them to justice while hunted by the very people who should be protecting her.

I've been calling this novel Queen's Justice for some time now, but I'm changing the title to Justice Rising. It hardly matters, though, since any publisher who buys this novel will probably change the title to something else.
