Once again, Egan (Phoresis, 2018) demonstrates his mastery of short-form science fiction. In Perihelion Summer, he takes on climate change from a unique angle—a micro-black hole passes close to Earth, changing its orbit and making the seasons more extreme and deadly, with swaths of the planet rendered uninhabitable. A group who built a self-sustaining aquaculture rig in the Indian Ocean to ride out the black hole now find themselves needing to navigate dangerous seas in search of survivable temperatures. Egan packs quite a lot into such a short book: science and engineering, family relationships and personal conflicts, global politics and danger. He presents a human tapestry in a time of disaster through evocative highlights of how people adapt to sudden crisis. This is a warning for how bad things could get if climate change is left unchecked. It’s a cautionary tale of the need for us to be prepared. But it’s also a beacon of hope—a story of survival at great cost. Difficult and painful as it may be, we find a way.

Moreci’s second novel in his Black Star Renegades series (Black Star Renegades, 2018) is even more compelling than its predecessor: action packed and funny, with more emotional resonance. We Are Mayhem deepens established characters’ relationships and explores how they inhabit their world. The narrative follows two alternating story lines—Cade, searching for answers to help him control the Rokura, and Kira, leading the rebellion against Praxis. Each chapter ends with a cliff-hanger, and there are several surprise reveals and an unexpected ending. Though occasionally the novelty of Moreci’s characters and ideas outpace his unsophisticated writing style, readers who are hooked will be eager for the next installment.

**STARRED REVIEW** Titanshade is a city running out of oil, and there’s a scramble to find alternative energy sources. When a delegate central to delicate negotiations is brutally murdered, it threatens to upend the future of the city. But no one knows who wanted the delegate dead or why, and a disgraced cop must descend into a complex underbelly of crime and political machinations to uncover the truth. What he discovers could cost him what he holds most dear. Titanshade is entirely unique: it’s a gritty noir murder mystery on an alien world with multiple species, a strange form of sorcery, a powerful religion, and large-scale political intrigue. And it’s set in the 1970s, with pay phones, 8-track tapes, racial tensions, and arguments about disco music. What’s amazing is how good it is at being all of these: the genuinely compelling mystery lives in a hugely original sf world and an immersive historical milieu. Moreover, debut novelist Stout is smart enough to let his characters live in this world without trying too hard to show it off. The setting just is, without effort, and that makes it eminently believable. This book should appeal equally to both sf fans and noir aficionados.

Terminal Uprising cements the reputation of the Janitors of the Post-Apocalypse as an exciting and rewarding series. The second entry (after Terminal Alliance, 2017) picks up four months after the end of the first. This time, Mops and crew are headed to Earth, the world of feral humans, and they’re accompanied by an unexpected ally. What they discover upends much of what they thought they knew about humanity’s downfall and could tip the balance in the war between Krakau and Prodryans. As always, their expertise in the custodial arts serves them well in unexpected ways. (Even better: librarians help save the day.) This book is plenty funny but less overtly jokey than the first one. The story is more interesting, and the character development is more multifaceted. Hines has grown confident in this world, and he continues to expand it in fascinating directions. The narrative takes a bit to establish momentum, but the latter half is quick and exciting. Overall, a strong edition to an excellent series that will appeal to fans of Becky Chambers.

This title has been recommended for young adult readers:

YA/General Interest: Humor and Hitchhiker’s Guide sensibilities make this series a good fit for sf-loving teens who aren’t put off by salty language.
