The Risvere

Okay, this is kind of a test book to see if I have the endurance and skills to write a book, so please comment what you think about it, suggestions are also welcome! Thanks!
Amber Lynora is training to become part of The Risvere, she wants to protect the world from the Keepers and fight for her people, but when Amber finds out that The Risvere's intentions aren't to protect, but to control, she, her brother Zev, and her best friend Deora set out to save everyone from two evil forces that threaten the safety of everyone. Death looms over their shoulders every second of the way, but Amber, with the help of her friend and a determined rebel, believes she can put a stop to the tyranny of The Risvere.
