edit data

International bestselling author I. C. Cosmos loves storytelling and has dreamed of being a writer for as long as she can remember.

Before turning to writing fiction, she was a business consultant and a director of an expertise center for forensic psychiatry, which was a marvelous training for creating fictitious villains.

I. C. writes thrillers in two series, The Alex Demarchelier series (The Wall, The Deal, The Code, The Enabler), and The Helen Dillon series (The Project, The Curator, Nemesis). While each series can be enjoyed on its own, they are intriguingly linked, sharing a cast of characters who move between both worlds. Dive into their narratives and uncover the connections for yourself! :-)

I. C. and her husband live in Baltimore.
