To Say Nothing of the Dog

To Say Nothing of the Dog

By Connie Willis

Time travel is real and it's terribly important for the students of Oxford University in 2057. Historians-in-training are able to leap into the past to study it firsthand, which is what Ned Henry spends most of his time doing. He's looking for the location of the “Bishop's bird stump,” but his journeys have left him in need of a vacation. A relaxing trip to Victorian England seems the perfect solution. But time travel comes with a whole heap of problems, and any incongruities in the timeline could lead to disastrous changes for Ned's present and future.

Grotesque, carnivorous, and over seven feet tall, these plant creatures are ready to dominate humanity after being exploited for years for their oil. It's up to the few remaining sighted survivors to prevent both an alien takeover and the dictatorial plans of a despot human.

A Fall of Moondust

A Fall of Moondust

By Arthur C. Clarke

The moon has long been colonized by humans, becoming both a hub for scientific research and a tourist trap for the exceedingly rich. A lunar cruise takes journeys across one of the lunar seas, akin to jet-skiing on Earth. But on one cruise, a moonquake causes a cavern to collapse, leaving passengers stuck inside with limited air and dwindling hope of survival. Captain Pat Harris and his chief stewardess Sue Wilkins must find a solution while keeping their team stable. Time is running out, the temperature is dropping to 200 degrees below, and the lunar dust of the Sea of Thirst threatens to smother them. Worst of all, it seems like nobody knows where they are…

Into the Drowning Deep

By Mira Grant

In 2015, the Atargatis set off on a voyage to the Mariana Trench to film a “mockumentary” on the mythic creatures that inhabit the deepest, darkest parts of the ocean. The bottom of the sea contains some of the least explored parts of our entire planet, and it seemed like the ideal location for Imagine, a shlocky entertainment company that specializes in horror movies. But the ship was lost at sea. Some thought it was a hoax to promote their movies. Seven years later, a new crew has been assembled to look for answers. For Victoria Stewart this is a voyage to uncover the fate of the sister she lost. For something happened in the deep and the secrets they reveal could come with a price.

Leviathan Wakes James S. A. Corey

Leviathan Wakes

By James S.A. Corey

Even if you're not familiar with the The Expanse book series, the unfortunately canceled TV series helped to show that Leviathan Wakes is one hell of a space thriller. The first book in the long-running series establishes a future where humanity has colonized the solar system. Tensions are fraught between Earth, Mars, and the asteroid belt that separates them, where miners live and are ostracised as low-class outsiders by the rest of the system. The class conflict comes to a boiling point when ice miner Jim Holden and his crew stumble on a derelict ship which contains secrets that could destroy the fragile peace of their small corner of space. Joining Holden is Detective Miller, on the hunt for a girl who might be the key to everything they're investigating.
