Plagued by the creeping loss of her memory, diplomat Bréone Hemmerli continues to negotiate peace in an increasingly climate-devastated world. The Necessity of Stars brings the alien Tura to Bréone's Normandy garden, a place removed from the world's ruin. Within the garden's shadows, Tura will show Bréone a way forward, even if she can't remember it. The Necessity of Starsby E. Catherine Tobler is a thoughtful tale of memory loss, politics and climate change.
