A Map of Vanished Stars

A melting glacier in the Altai Mountains has revealed something that shouldn't exist: a Bronze Age burial complex spiraling down into the ice, each tomb older than the last, descending toward a structure built millennia before civilization. Dr. Strand, a glacial archaeologist with nothing left to lose, races a rival expedition and a collapsing mountain to reach the bottom—where proof of a lost scientific civilization awaits anyone brave or desperate enough to claim it.
