Jo Walton

Jo Walton

Jo Walton has published twelve novels, with a thirteenth, Necessity, out this summer. She has also published three poetry collections and an essay collection. She won the John W. Campbell Award for Best New Writer in 2002, the World Fantasy Award for Tooth and Claw in 2004, the Hugo and Nebula awards for Among Others in 2012, and in 2014 both the Tiptree Award for My Real Children and the Locus Non Fiction award for What Makes This Book So Great. She comes from Wales but lives in Montreal where the food and books are much better. She gets bored easily so she tends to write books that are different from each other. She also reads a lot, enjoys travel, talking about books, and eating great food. She plans to live to be ninety-nine and write a book every year.

Jon Singer

Jon Singer

Jon Singer is a man of many talents, but foremost among them are his love for building lasers and making pottery - but usually not both at the same time. He makes lasers out of the most unusual materials sometimes, but the results are amazing. You can see a video of him making one here.

His webpage is at www.jonsinger.org where you can find a lot more about his work.
