Alpha Prince Unexpected Mate

"Mate!" He heard his wolf growl. 
Lancelot's eyes dropped to the place she shook his palm. 
'You have got to be kidding me.' 
********
She had lost everything in just one day her job she tried so hard to find, her fiance she dated half of her life, and what remained of a relationship with her twin sister. The one thing she could not afford to lose was what was left of her dignity — certainly not at a wedding that should have been hers. And that was why she needed him, the handsome stranger across the road. 
What Roxanne Harvey didn't know was that this stranger was here to stay. 
Lancelot Dankworth, Alpha Prince of the London Pride Pack couldn't believe his eyes. The crazy American woman yelling at his assistant caused his wolf to growl possessively for the first time in 26 years. 
He never believe he would be capable of ever loving anyone else, but why can't he seem to keep his emotions in check whenever he was around the crazy American woman?
He loves being alone, he had always been, but why is suddenly being apart from her driving him nuts?
They should not be together. He is an alpha prince and she is a human woman. However, this fact does not stop him from falling head over heels in love with her. 
With Lancelot's dark past and numerous enemies, he struggles to protect her from his countless enemies, as well as himself.  Would their bond be  strong enough to conquer all? Or would they lose each other along with themselves?
