- M. John Harrison's novel The End of Everything is set after an obscure crisis that reshaped the world, following tide‑line collector Phillip who discovers a shape‑shifting sea creature.
- Joseph Eckert's The Traveler follows Scott Treder, whose daily “slippages” begin at 7:52 am and double in length, sending him forward through years while his son Lyle ages and tries to catch him.
- Isabel J. Kim, a Nebula‑award‑winning author, explores immigration in Sublimation, where emigrants leave a literal “instance” of themselves behind and can later reconnect; protagonist Soyoung Rose Kang must confront her Korean instance after her grandfather’s death.
- Adrian Tchaikovsky's Green City Wars is set in a solar‑powered future where “Little Helpers” – artificially enhanced animals – keep luxury green cities running, and the plot follows freelance raccoon investigator Skotch on a new case.
Why it matters: Sci‑fi readers and publishers benefit as these four June releases deliver fresh takes on climate dystopia, time‑travel family drama, immigrant identity, and AI‑augmented ecologies, expanding genre diversity and market appeal.
