Star Thief

Jake Vitades takes rich aliens on trips to dead ruins. He gives them adventure and a chance at finding valuable tech. But looting ancient ruins is dangerous. And finding tech is rare. However rich aliens don't mind bad odds. They like adventure on dead worlds. Whether they live or die in their adventures Jake does not care. He insists on advance payment. As an archaeologist specializing in dead cultures he prefers present day funds versus theoretical tech loot. It's also safer. He and his crew like being safe and rich in a galaxy overrun by empires that don't give a damn for new arrivals like humanity. But the world they are aiming to loot has surprises waiting for them. Still, Jake does what he is paid to do. Which is to help aliens loot dead worlds. No matter what happens.
