I’ve not read anything by Jack McDevitt before. His next novel, Thunderbird, looks quite interesting, though:
On a Sioux reservation near Devils Lake in North Dakota, a working stargate dating back more than ten thousand years has been discovered. Going through the gate leads the traveler to three mysterious destinations: an empty garden world dubbed Eden, a strange maze of underground passageways, or a space station with a view of a galaxy that looks like the Milky Way.
The race to explore and claim the stargate quickly escalates and those involved divide into opposing camps who view the teleportation technology either as an unprecedented opportunity for scientific research of a disastrous threat to nation, not to mention planetary, security. One thing is for certain though — questions about what the stargate means for humanity’s role in the galaxy cannot be ignored.
