Shadowrun: Fire & Frost - Shadowrun, #1

THE COLDEST SHADOWSArcano-archaeologist Elijah knows that digging into the past can be its own reward-or peril. When he's hired to find an ancient map purported to lead to a mysterious location at the bottom of the world, his professional curiosity is roused. But his quest to simply get his hands on the map is more dangerous than he expected-even for a shadowrunner. He and his team of runners-everything from a goblin rigger to a troll street samurai-follow a murky trail from the ruins of Chicago to the jungles of Amazonia.
Along the way, they discover they're not the only ones looking for this map-and that it may lead to a treasure even greater than anyone could have known. Elijah and his crew plan to get both the map and to its riches first-assuming they can survive one very dangerous road trip.
