The Heir of Shadows by Candice Wright

There was a little girl, who had a little gun, pointed right at the center of her forehead.
When she was good, she was very, very good
Because if she was bad, she was dead.
Raised by a monster, rescued by a liar
The life Ava escaped from is a memory she would like to forget
But the past never stays buried for long and when a tragic event forces Ava back home
The monster is waiting to finish what he started.
With fragile bonds put to the test, Ava will need to find the strength to fight back, putting her faith in the club she was never a part of and a President who is more of a stranger to her than a brother.
Blood might be thicker than water, but its blood that attracts sharks
And if she doesn’t learn to stay two steps ahead of the deranged killer who hunts her, she’ll drown.
In a world of bloody secrets and twisted legacies, only one truth remains:
To prevail, one of them must die.
But who will survive?
The Fallen King, or his Tainted Heir?
