The final instalment of The Book Of Dust trilogy. We know quite little about it so far, but it could bring Lyra further East and also... shhhh... Spoilers!
Based on past interviews with the author, the name of the book could be The Garden of Roses or Roses from the South, but will have somehow to do with roses. As of May 2021, about 132 pages had been written.
Over the last few days of 2022 and the first of 2023, the author successively stated that more than 50% of the book had been written, and that, with a bit of luck, it would be completed "by the end of the year". More to come...
