Tarryn Fisher was born in 1983 and is a South African-born novelist currently based in Seattle, Washington, United States. She primarily writes within the romance, thriller, and new adult genres. Fisher is renowned for her New York Times bestselling novels The Wives and The Wrong Family.

Fisher's writing philosophy is intriguing. "I would like to write a novel that every, single person loves, but not even J.K. Rowling could do that," she says. Instead, she aims to create stories that evoke strong emotions in readers. Fisher believes that sadness, when intertwined with regret, becomes a powerful and dominating force. She has a peculiar fascination with villains, citing Mother Gothel, Gaston, and the Evil Queen as some of her favorites, particularly for their vanity, a trait she amusingly finds in herself.

Her personal interests include a love for rain, Coke, Starbucks, and sarcasm. She harbors a disliking for poorly chosen adjectives and the word "smolder". Fisher has a candid message for her readers: "If you read my book—I love you. If you hate my book—I still love you, but please don't be mean to me; I'm half badass, half cry baby."
