Lucas is a writer, artist, game designer, and tech support guy living in Seattle, WA. In 2015, he published his first book, the humorous Japan travel guide/memoir, Shakotan Blue. In 2024, he cowrote Legendary Puns with his fellow Kelleher brothers, and also provided the book’s illustrations.

Luke makes a silly little webcomic called Liquid Crystal Disco. Sometimes he turns his illustrations into ridiculous merchandise. So if you like weird t-shirts and junk, check out the shop page.

He also dabbles in game development, which you can see on his itch.io page. He can be found on social media platforms—such as Instagram or Bluesky—under the handle ‘propelleher’.
