Imagine if all our legends are true? A rousing, fast-paced novel of time travel unlike every other, from acclaimed writer Wil McCarthy. What if our legends are older than we think? All the Stone Age has left out are rocks and bones; all the materials have got rotted away, departing no track. But what if ‘cave males’ never existed, and the Rock Age was a period of great class still preserved inside our oldest stories? In an excellent and dangerous brain hacking test, Harv Leonel and Tara Mukherjee are going to discover entire lifetimes of individual memory coded in our genes, and reveal historic legends – from knights and trolls, to flood myths, to the birth of mankind itself – that are as actual because they are deadly. Before disaster erased the coastlines and river valleys from the Antediluvian age-before the Flood-men and women struggled and yearned and innovated in a world of savage contrasts into which Harv and Tara are thrust, unprepared. Can their science be adequate to save them?
