Solaris scoops ‘witty’ space opera from Caspar Geon

Solaris has scooped The Immeasurable Heaven by Caspar Geon.

Editor David Thomas Moore acquired world all-language rights from Ed Wilson at Johnson & Alcock for publication in July 2025. 

The synopsis for The Immeasurable Heaven reads: “In a long settled galaxy, a race known as the Sovereigns possesses the means to visit parallel realities, appearing inside the body of someone, or something, else. The Well, where horrors are flung, runs through the realities like a fissure, and the king-turned-sorcerer who’s been trapped there for more years than he can say trudges the wastelands for a way out. When news breaks of a priceless map of the realities, a kaleidoscopic cast of alien characters race each other across reality to the Well – and quite possibly to their own deaths.” 

Geon commented: “I’m so happy that The Immeasurable Heaven has found such a good home with Solaris, and looking forward to sharing my strange tale of another galaxy next year.”
Moore called the novel a “vast and cosmic, smart and witty, pacy and fun, human (ironically given there are no humans in it) and personal”. He added: “[It is] one of the most original science fiction books you’ll read.”
