The Red Crown by Jade R. Evans

So much is broken.
But the men who rule the Knights of Caliburn—the ancient order my four protectors answer to—don’t know that. The White Brothers of St. Vincent have no idea what their sworn knights have done for me: vows abandoned, blood spilled, a sacred mission twisted beyond recognition.
And time is running out.
Kingston is fracturing under the weight of his choices. Kai’s playing a dangerous game with men who never lose. Lanz is fading in ways that terrify me. And Callahan—steady, loyal Callahan—is being tested in ways that could shatter us from the inside.
We can’t hide for long. Because something else, something bigger, is holding Caliburn’s campus frozen.
And there are older powers stirring. A lady in the lake. A riddle with no easy answer. And a question I’ve been running from my entire life.
Who do you think you are?
I’ve spent so long hiding. Apologetic. Trying to just be normal. But when fire and reckoning come to Caliburn, no one else can answer for me.
Not my knights. Not my enemies. Not even God himself.
Only me.
