Viper's Vixen: Off-limits obsession, his vixen (Dublin Falls' Archangel's Warriors MC #7)

Viper:
Viper didn’t get his name for his disposition.
He got it from his days as a Navy Seal.
He could be the silent killer waiting to strike.
He was untamed and loved his brothers in the MC
Then he met the woman who tried to take off his head.
The one who wouldn’t let him forget her.
She was a president’s sister. Off limits.
But he’d seen her and now he wanted her.

Harper:
Her helping her brother and the Warriors led to her being a target.
Their enemies tried to kill her.
The Warriors took her in to protect her.
This put her near him every day.
The one man she couldn’t forget.
The one she’d been obsessing about since he found her naked that day.
A man who made her want to explore a relationship.
If only he wanted the same.

However more enemies are out to kill her. Once one is gone, someone else seems to have taken their place. Had they missed some one? Could Viper find the threat and eliminate it before his Vixen was taken from him forever?
