Splintered Suns — Michael Cobley

A speed of light space adventure novel of a treasure hunt that could unlock all the wonders of a vast and advanced civilization's lost technologies.

For Pyke and his crew it should have been just another heist. Travel to a backwater desert planet, break into a museum, steal a tracking device then use it to find a ship buried in the planet's vast and trackless sandy wastes.

Except that the museum vault is a bio-engineered chamber, and the tracking device is sought-after by another gang of treasure hunters led by an old adversary of Pyke's, the devious Raven Kaligara. Also, the ship is quarter of a million years old and about two kilometers long and somewhere aboard it is the Essavyr Key, a relic to unlock all the treasures and technologies of a lost civilization...
