Red Queen

"The Red Queen series is about a girl living in a world where the colour of your blood determines your status. She has red blood, which means she is powerless and about as important as dirt. She runs into a guy with silver blood, which means that he has powers and is way more important than her. By powers I mean powers quite literally, some people with silver blood can control water, others can control fire. Some are very agile and some can bend light. The list goes on. This encounter sparks an event that changes her whole life, and reveals closely guarded secrets that could change the whole world."
