Mary Cronos is an female author of fantasy, crime, and mystery fiction, a visual artist (photography, illustration, and design), and a streamer covering creativity, reaction content, and gaming. She loves using her "creative chaos" to conjure images in people's minds and before their eyes – whether through her art or her books.

Her books invite readers to travel to Scotland, to otherworldly realms, or to the house next door – always with a touch of the supernatural, varying doses of humor, and a generous amount of meta-commentary. Her artistic range spans everything from photorealism to chibi art, created both traditionally and digitally; she prefers photographing cosplayers or nature; and her design work focuses primarily on book covers across all genres. Occasionally, she combines these skills to create books that sit somewhere between art and literature, such as her Geekbook or Booksbook.
