Calculating Stars - Pre-Order


This listing is for the pre-order of Mary Robinette Kowal’s inspired yarn! Pre-orders will ship late July - early August.

Inspired by Mary Robinette Kowal's newest Lady Astronaut book series, The Calculating Stars and The Fated Sky, our friends at Why Knot Fibers created two custom gradient colorways that will have you seeing stars! The Calculating Stars book is already the #1 New Release for Alternate History Science Fiction and we think you’ll love the yarns to the Moon - and back!
