Adam Christopher has announced the release of his new novel Shadow's Call. Big news is that it will be published for Tor US. As for what we can expect in Shadow's Call, here's the small summary:
Shadow’s Call is a dark space opera set on a distant, derelict space station, bathed in toxic radiation from a nearby star, where a washed-up Fleet commander must battle a sentient mechanical spider race and its sinister allies with the help of a long-dead Cosmonaut and a sexy but troubled celebrity asteroid-miner.
Shadow’s Call is due out in summer 2013.
