Tyler Feder (she/her) is a Chicago-based artist whose work explores Big Feelings, feminism, and pop culture. She wrote and illustrated the acclaimed young adult graphic memoir DANCING AT THE PITY PARTY and made her picture book debut with BODIES ARE COOL. Tyler has been living with The Noodles (aka clinical anxiety) since she was a little girl, and she loved getting to work on ARE YOU MAD AT ME? with her little sis and BFF Cody! Tyler lives and works out of a cozy, pink-walled apartment in Chicago with her fluffy white cat Mitzvah. (Can you spot him in the book?)

Cody Feder (she/her) is a Chicago real estate professional and social media marketing expert with a lifelong passion for mental health advocacy. After spending her childhood, teens, and twenties battling anxiety, depression, and a serious eating disorder, she has accumulated a wealth of firsthand knowledge about mental illness and body image. Her goal is to use her background to help the next generation of "Codys" grow up with a strong foundation of self-confidence so they won't struggle the same way she did. Are You Mad at Me? is her first book, co-written with her older sister and dearest friend, Tyler. In her spare time, Cody loves decorating her apartment, finding ridiculous deals on designer accessories, and snuggling with (and learning from) her cheerful and carefree puppy, Georgia.
