When Trisha Speed Shaskan was a girl, she wanted to become a superhero. Her mother gave her a Wonder Woman costume. Her dad crafted her a tiara and bracelets out of metal to match. Trisha imagined she could fight evil, fly an invisible airplane, and get anyone to tell the truth. While she didn’t grow up to be Wonder Woman, she still uses her imagination to write stories and to teach creative writing. Trisha has taught creative writing to children and adults for thirteen years. She has published 26 books for children, and more are forthcoming. She has an MFA in creative writing from Minnesota State University, Mankato. Trisha currently lives in Minneapolis with her husband, Stephen, and their cat, Eartha, named after Eartha Kitt, famous for her role as Catwoman.
