“Creepy, scary, sad, and squelchy” aren’t words that seem to go well with “cozy fantasy,” “sapphic romance,” or “dark comedy.” But Nebula and Locus award-winner John Wiswell blends all those elements into his debut novel, Someone You Can Build a Nest In. One of Polygon’s most anticipated science fiction/fantasy novels of 2024, the book, now on shelves, centers on a shape-shifting monster. Shesheshen haunts her local town, Underlook, until she connects with a human woman whose gentleness surprises her. Smitten, Shesheshen plans to show her love by implanting parasitic eggs in her crush object.
