Cairo Elizabeth 'Kai' Corbyn is an agent with Mossad.
Well, she was one. She was very, very good one for a fair number of years. And then she wasn't.
As a promo on her chronicler's website puts it:
"Kai Corbyn was trained by the world's elite to be invisible, precise, and above all, deadly.
"She was Mossad's most effective assassin. But when a routine operation goes terribly wrong and she's forced to disappear for good, only one man knows she's still out there - and just what she's capable of.
"Given a new lease on life, Kai does what she does best. Choosing her contracts carefully, she builds a lucrative business hunting down targets - for a price. Soon, the worst of the underworld is facing a foe who won't stop before she picks them off, one by one...until she's offered a contract on someone from her past.
"Thrown back into a world dominated by intrigue, money, and power, Kai must join forces with the man she saved to uncover the truth. But those who want them dead will stop at nothing to prevent that truth from getting out. Drawn back into her old world, Kai embarks on a new operation. Only this time, she's playing by her own rules. And no one stands a chance."
When we meet her, save for a brief excursion she does to Romania for a mission several weeks earlier, she is living somewhat off the grid in beautiful Mataro, Spain on the north edge of the Balearic Sea. The home she had there was hers, bought and paid for in secret so no one would associate it with her. Though she would go on to work for Israel in its intelligence community, Corbyn was born and raised in the Andalusian region of the Iberian Peninsula.
Corbyn is a very attractive woman still in her relative youth with green eyes and a "slender frame" who moves with grace and ease but is capable of doing so "with speed and silence born of practice".
She can pick and choose her targets but when she accepts a contract, the designated individual is as good as gone.
