HOOKED ON ZERO

Zero is a fiery assassin contracted to kill Alex, a billionaire scientist, but on her way, she has a ghastly accident. 
She is contracted by someone to get rid of a billionaire scientist. Her plans go down the drain when she has a ghastly accident.  In her dire state, a stranger, Alexander,  helps to pay for her extensive medical bills and makes sure she has a fighting chance at life.
With Alexander's heart is still grieving for his late wife who just died of womb cancer, he goes ahead and perfects the drug that would later become a life saver for many people in the early stages of cancer. 
As the days run into weeks, Alex finds out the loss of his wife is not as rife as it used to be, thanks to Mia's presence in his home. Both of them are not able to fight off their growing attraction for each other.
As is usual of situations like this, drama, attraction and so much in between, takes place.
You see, Zero has lost her memory, she doesn't remember a thing.  That's probably where the problem lies. 
A whole lot of drama later and she finds out things are not as they seem. Someone has been yanking her chains.
That someone has to pay!
