Puck Koper is an illustrator from Rotterdam in the Netherlands. She graduated from Willem de Kooning Academy in Rotterdam with a BA in Illustration in 2012, and in 2017 she gained a distinction in her MA in Children’s Book illustration from Cambridge School of Art. Puck loves drinking tea, ice skating on frozen lakes, cycling and dancing. If she could wish for one thing it would be to have a dog to keep her company in her studio. Puck lives in Rotterdam on the most Dutch street you can imagine, complete with sailing boats, drawbridges and a windmill. Where Is Your Sister? is Puck's debut picture book.
