The Slavic Shamble - Larouverse, #3

Marco Conti was convicted of knowing Lucia Ricci, who was found guilty of the murder of his father, Oronzo Conti. He served his term in jail successfully and was released after his behaviour was monitored. Feeling bad about his past, he sought shelter with a hidden organisation that claimed to achieve global peace by eliminating the person they considered responsible. But, again, he was incorrect until he travelled to Greece.
He joined an American corporation that produced medications to improve people's health.  He met Anastasia Honchar, one of the firm scientists who worked on the newest medicine and helped assess its efficacy. Can Marco tolerate the drug's adverse effects while using it, or will Anastasia keep him sane?
