Arianne Costner is a middle grade author, past English teacher, and Tetris champion who firmly believes writers should crack up at their own jokes. She lives in California with her husband and two toddlers bent on destroying her house. When she’s not writing, she can be found playing the piano, composing music, or trying out new recipes. Arianne previously participated in Pitch Wars as a mentee, where she finally found her writer tribe. Arianne is represented by Amber Caraveo of Skylark Literary.

For Pitch Wars 2018, Arianne Costner is co-mentoring with Adrianna Cuevas.
