Gitty Daneshvari was born in Los Angeles to an Iranian father and an American mother. As a child, she talked incessantly, feeling the need to comment on everything around her. While initially charmed by her verbose nature, her family soon tired of the constant commenting. This led her to writing, which she preferred over talking since she didn't need anyone else to do it with. She currently resides in New York City and, yes, she still talks too much.

After mining her extensive list of childhood phobias in the SCHOOL OF FEAR series, Gitty decided to revisit the time she was rejected from her school’s Talented and Gifted program for being too average in THE LEAGUE OF UNEXCEPTIONAL CHILDREN series. She also spent a few years with the MONSTER HIGH: GHOULFRIENDS series. Gitty has sold over 5 million books worldwide. She currently lives between Madrid, Spain, and New York City with her family and her French bulldog Marvin, as well as a shrine to her late English bulldog Harriet. She's really into bulldogs, books, her family, and Chinese food.
