Serpentine by Philip Pullman

Serpentine is a very short tale by Pullman, written for a fundraising concern in 2004, and finally published in 2020 as a small book with illustrations by Tom Doxbury. It basically fills in a small gap of the story of Lyra Silvertongue after the events of the three-volumed His Dark Materials. As a story it is even less substantial than the similar small books Lyra's Oxford (2003) and Once Upon a Time in the North (2008). But it has a pleasant epilogue-styled feel, and whets one's appetite for further tales in the same universe.
