Red Queen by Victoria Aveyard (Red Queen #1)

In a world divided by blood—those with common, Red blood serve the Silver-blooded elite, who are gifted with superhuman abilities—Mare, a Red, discovers she has an ability of her own. To cover up this impossibility, the king forces her to play the role of a lost Silver princess and betroths her to one of his own sons. But Mare risks everything and uses her new position to help the growing Red rebellion, even as her heart tugs her in an impossible direction.

“It mixes fantasy with real life, which is exactly what I like to read. It’s also a series which expands on the world and characters.”
