Mira Chen is a mathematics professor with a $302,847.63 problem. Her mother's medical debt — to the cent. So she does the only rational thing a woman with a genius-level IQ and no ethical flexibility left can do.
She robs a crime lord's poker table.

The FBI wants her testimony. His enemies want his empire. Her mother's life depends on money that hasn't been clean since it was printed.
And somewhere between the math and the man, Mira stops counting.
That's the part that terrifies her.
Counting Sin is a dark mafia romance with a mathematician heroine who has full agency, a morally gray hero who falls first, high heat, and a happily-ever-after worth every felony it cost.
