Ilona Andrews is the combined pen name of Ilona Gordon and Andrew Gordon, an American writing team specializing in urban fantasy, science fiction, and paranormal fiction. Their collaborative journey began at Western Carolina University, where they met and eventually married. They started writing together, facing initial rejections before their debut novel, Magic Bites (2007), launched the popular Kate Daniels series.

Their writing process involves sitting together at one computer, with Ilona drafting female characters' dialogue and Andrew the male characters', while they collaborate on plot points and action scenes, drawing on Andrew's judo background. Their work is deeply influenced by world mythology, with Ilona's upbringing in the Soviet Union providing exposure to Slavic folk tales and Andrew's studies in history and mythology. They have since published numerous novels and novellas across several series, including Hidden Legacy and The Innkeeper Chronicles, and have explored both traditional and self-publishing models.

Ilona Gordon, originally from the Soviet Union, was a gifted student who received a scholarship to attend boarding school in Georgia, USA. She later studied biochemistry at Western Carolina University. Andrew Gordon, born in Florida, grew up in North Carolina and served in the United States Navy before also attending Western Carolina University to study history and political science. The couple met in a university writing course in 1994, and their collaboration began through editing each other's work. Their marriage in 1995 solidified their partnership, viewing their endeavors as a team effort, a perspective influenced by Andrew's military service.

The writing duo Ilona Andrews works side-by-side, sharing a single computer. Ilona typically writes the initial dialogue for female characters, while Andrew handles the male characters' lines. They collaboratively plan action sequences, with Andrew's judo experience informing these scenes. Their writing is significantly inspired by global mythology; Ilona's childhood included Slavic folk tales, and Andrew's academic background encompassed history and mythology. They actively seek new narrative material by visiting used bookstores. This blend of personal background and academic interest fuels the rich world-building found in their fiction.

Ilona Andrews' career began with the publication of Magic Bites in 2007, the first book in the successful Kate Daniels series. They have since authored over 40 novels and novellas across various series, including the Hidden Legacy and The Innkeeper Chronicles. The authors have navigated both traditional publishing and, more recently, embraced self-publishing, particularly after their novel Blood Heir achieved significant success. This shift allows them greater creative control and direct engagement with their established readership. Their work spans urban fantasy, science fiction, and paranormal fiction, often exploring complex magical systems and societal structures.
