Of Rioters and Royals by M.L Greye

Emry is a Royal - a princess of Enlennd. As is tradition, she must have a knight at her side as her protector. The only way to appoint one is through The Trials. Her Challengers from the five regions of Enlennd must compete for the infamous title of Princess's Knight. The problem, though, is that the people of Enlennd are split into two categories: Rioters and Royals. Finding the perfect knight may be the last of her worries. War is coming to Enlennd. Declan is a Rioter. An upriser. An anarchist. He mistrusts the Jewels - the sovereign family of Enlennd. Yet, he is offering himself up as a Challenger in The Trials. The Mistress, leader of the Rioters, has a mission for him. The first step is for him to become the Princess's Knight. He is ready for the task, until he actually meets Emry and discovers that betraying her would be much more difficult than he'd thought.
