Sarah Hines Stephens has been a children's book reader, editor, seller, buyer, author, copyeditor, ghostwriter, and speaker for many years-and she's still most of those things. Her home is in Oakland, California, with her husband, two kids, and two dogs.

Dario Brizuela was born in Buenos Aires, Argentina, and as a teen he began studying in an art school-doing drawing, sculpture, painting, and more. After discovering superhero comic books, his goal was draw his favorite characters.

He broke into comics by working for publishers like Dark Horse Comics, Image, Mirage Studios, IDW, Titan publishing, Soleil Productions, Viz Media, Little, Brown and Company, DC Comics, and Marvel Comics, and for companies like Hasbro and Lego.

His comic book and illustration work in the U.S. and Europe includes: Star Wars Tales, Dioramas, Ben 10, Super Friends, Justice League Unlimited, Voltron Force, Batman: The Brave and the Bold, Transfomers, Mini Hulks, Gormiti, Superhero Squad, Scooby Doo, and Beware The Batman.
