Moving to a space station at the edge of the galaxy was always going to be the death of Hanna's social life. Nobody said it might actually get her killed.

The saga that began with the breakout bestseller Illuminae continues on board the space station Heimdall, where two new characters will confront the next wave of BeiTech's assault. Hanna is the station captain's pampered daughter, Nik the reluctant member of a notorious crime family. But while they are struggling with the realities of life aboard the galaxy's most boring space station, little do they know that Kady Grant and the Hypatia are headed to Heimdall, carrying news of the Kerenza invasion.

When an elite BeiTech team invades the station, Hanna and Nik are thrown together to defend their home. But alien predators are picking off the crew one by one, and a malfunction in the station's wormhole means the space-time continuum may be ripped in two before dinner. Soon, Hanna and Nik aren't just fighting for their own survival. The fate of everyone on the Hypatia - and possibly in the known universe - is in their hands.

But relax. They've totally got this. They hope.
