Thunderbird

The Nebula Award–winning author of the Alex Benedict novels and the Priscilla Hutchins novels returns to the world ofAncient Shores in a startling and majestic epic.
 
A stargate more than ten thousand years old has been discovered on a Sioux reservation in North Dakota. Travel through the gate leads to three equally mysterious destinations: (1) an empty garden world, dubbed Eden; (2) a maze of underground passageways; or (3) a space station with a view of a galaxy that appears to be the Milky Way.
 
The race to explore and claim the stargate quickly escalates, dividing those involved into opposing camps who view the teleportation technology either as an unprecedented opportunity for scientific research or a disastrous threat to security. In the middle of the maelstrom stands Sioux chairman James Walker. One thing is for certain: Questions about what the stargate means for humanity’s role in the galaxy cannot be ignored.
 
Especially since travel through the stargate isn’t necessarily only one way...
