Growing up in a small town with no cable (and parents who were teachers), reading was the only thing to do. Since then, Christianne Jones has read about a bazillion books and written more than 50. Christianne works as an editor and lives in Minnesota with her husband and three daughters. Born in 1974 in Nantes, France, Gerald grew up in nine different cities around the land of cheese. He graduated from the National School of Applied Art (also called Olivier de Serres) in 1998. Gerald's creativity blossomed at a web design company, an event studio, a video-games studio, and then several animations studios. Aside from illustration, Gerald has many other interests, including managing the French Comics Artists association "Rendez-Vous" (which published its first book at Akileos publishing in 2009), or co-leading with the Japanese Artist Daisuke Tsutsumi the artistic and charity project "Sketchtravel," a real sketchbook shared by 70 illustrators from all around the world. 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.
