Knox by Autumn Summers

Knox is a new member of the Wicked Kings. After a bomb goes off, they scramble to survive. However, Knox is worried, since he doesn’t know if things will get better. After he rushes to the hospital, he meets Demi, a nurse there.
They immediately hit it off, but Knox notices there’s something amiss about Demi. What happened to her? As they grow closer, Knox realizes the truth: that she’s being used and abused by her boss, and he wants to stop at nothing to save her.
When it’s revealed that there is another option, Knox quickly takes it, deciding to use that against them. But will it be enough to take him out? Will Knox stick around in the MC? Or leave after?
