Amie Kaufman and Jay Kristoff bring their Illuminae trilogy to an action packed, emotionally charged, edge-of-your-seat conclusion in Obsidio. Of course these are, essentially, all of the ingredients that readers of this series have come to expect. As with the previous books in this series, Obsidio is told through a collection of found documents, graphics and text, and this style continues to work well to create a very visual, cinematic feel. In a nutshell – the survivors of the previous books have no choice but to retrace their steps to Kerenza IV. Meanwhile, on Kerenza, the Beitech invaders have become an occupying force, using the remaining population to mine the resources they need to repair their ships and leave. One of the occupying force is Rhys Lindstrom, ex-boyfriend of invasion survivor and insurgent Asha Grant, cousin of Kady, one of the heroes of Illuminae. Putting yet another, troubled romance at the centre of the action. But all of the surviving characters from previous books also have a part to play in Obsidio. This time, more than before, the young protagonists have to deal with a world where the adults just won’t take them seriously (but have to save the day…

Amie Kaufman and Meagan Spooner, together and separately have been staking out the science fiction corner of the young teen, young adult market. In the Illluminae Files, together with Jay Kristoff, Kaufman showed a willingness to recycle tried and tested science fiction tropes into a new format. Unearthed is a similar sort of hybrid – part Indiana Jones, part Tomb Raider, part Contact, part Arrival and part, well every science fiction novel that has humans exploring strange new worlds (with a dystopian back story that also involves a generation ship for good measure). And in the middle of it, two snarky, flirty, intelligent, likeable teens from opposite sides of the tracks who fall for each other while saving the day. An alien signal from a race called the Undying has opened the way to a barren planet called Gaia which contains potentially world-changing technology. Amelia is a sixteen-year-old scavenger who has gone to Gaia to find her fortune and Jules, slightly older, is a genius academic who wants to solve the riddle of the alien tombs. They meet cute and are forced to travel together. And while their attraction grows, they have to navigate a tomb by solving alien puzzles,…

The elevator pitch for Gemina goes something like this: imagine a cross between Aliens, Die Hard, Star Trek: Deep Space Nine and Romeo and Juliet. Not surprising given this is the sequel to the Aurealis-award winning Illuminae (reviewed here), a book that managed to mash up elements from Battlestar Galactica, 2001, 28 Days Later and possibly something by Nicholas Sparks. Gemina, a geek’s delight, has all of these elements and plenty more (even Firefly gets a shoutout). It advances the corporate conspiracy plot of Illuminae while focussing once again a few incredibly resourceful teens. At the end of Illuminae (spoiler alert) the survivors on the Hypatia are heading towards a wormhole that will jump them to a space station called Heimdall. Gemina opens on Heimdall on the eve on an invasion organised by the Beitech Corporation trying to clean up its mess by destroying the Hypatia. Hanna, the daughter of the station commander, Nik, a member of the House of Knives crime gang, and his cousin Ella end up being the only ones standing between the twenty-four armed to the teeth mercenaries and destruction of the Hypatia. Well, them an a bunch of hungry, slimy, four-headed aliens loose on the…

Looking for a great science fiction book? From political intrigue to young adult space adventure (with zombies) to the mind blowingly-weird here are the top five science fiction books reviewed on Pile by the Bed in the first half of 2016. Click on the cover for the full review:

Illuminae states its intention right from the cover, which is covered in scraps of partially redacted documents. The book itself is told through a series of recovered documents of varying types, many flagged with introductory comments. The form of narrative has been done before and it is worth saying at the outset that Kaufman and Kristoff do it very well. Despite lots of goriness and evil goings on, all swear words are redacted to keep this closer to PG than MA territory. The main characters are two seventeen-year-olds who have just broken up when they have to survive an attack that destroys their home planet – an illegal mining colony in the far reaches of the universe. They are rescued and end up on separate ships in a fleet of three trying to outrun a battleship bent on their destruction. Both are likeable characters – Kady the techno-hacker chick with a healthy disregard for authority and Ezra, the jock with a heart of gold – and the narrative constantly flicks between the two. Through all the mayhem that follows, their relationship issues are never far from the surface. Kaufman and Kristoff have fun with a bunch of sci-fi sub-genres. Illuminae…
