Roxy the Last Unisaurus Rex

Eva Chen is a first-generation Chinese-American who grew up in New York City. She blames her deviation from pre-med at Johns Hopkins University on a love of fashion and beauty instilled in her by her mother, whose perfect bob and lipstick made a permanent imprint on her impressionable young mind. Previously the editor in chief of Lucky, Eva has also written for ELLE, Vogue, Teen Vogue, Vogue China, the New York Times, and the Wall Street Journal. She is currently the head of fashion partnerships at Instagram, where she is guilty of the occasional duck-face selfie. Eva lives in New York City with her husband and two children. She is the New York Times-bestselling author of Juno Valentine and the Magical Shoes; A Is for Awesome; Juno Valentine and the Fantastic Fashion Adventure; 3 2 1 Awesome!; and Roxy the Last Unisaurus Rex.
