Formerly a children's book editor, Jen Arena has written over 50 books for kids, including Lady Liberty's Holiday. When she's not writing or editing, you can find her in her garden curled up with a good book, on the volleyball court, or at her local bookstore.

Lorena Alvarez was born and raised in Bogota, Columbia. Her work is influenced by the vibrancy and color of her home town as well as the experiences and atmosphere of the Catholic school she attended as a child.

She studied Graphic Design and Arts at the Universidad Nacional de Colombia. She has illustrated for Puffin Books, Faber & Faber, Usborne Books, Paragon, Boom! Studios, Nickelodeon and Disney.

Since 2008, she has been part of "La Procesion Puppet Club," an experimental puppetry group of illustrators and visual artists.
