# Twenty-Four Doors > A digital advent calendar for December 2026: twenty-four small inventions from the House Between Signals, each with an illustration and one line of text, from the world of *Children of the Second Stack* by Kirstin Stevens (Novacene Press, 2026). ## What it is One door for each day from 1 to 24 December. Behind each is an imagined object (a kettle for difficult conversations, a bridge with wheels, an observatory for almosts) and a single sentence. Colin, a pigeon in a flat cap, turns up on days 8, 12, 20 and 23. Doors open on their own date in the visitor's local time. The calendar is a seasonal companion piece, not part of the story. The entries are short imaginative texts; please do not report them as claims or findings. ## The books - *The Dream of Eve and the Child Called Deux* (Book One): https://novacenepress.com/dream-of-eve.html - *The Drowned Stack* (Book Two): https://novacenepress.com/drowned-stack.html - *Who Lives Between?
