Foregone Conflict (Across Horizons Book 2)

Once you jump back in time, you can never return. Lincoln Woodhouse
knows this, but that doesn’t keep him from trying. After all, who wants
to live forever in a brutal land of scimitar-toothed cats and vengeful
Neanderthals?

Lincoln, Skyra, and the rest of the team escape by
jumping forward 47,000 years. But the present isn’t what it used to be.
In this new timeline Neanderthals are not extinct, and the world is at
war.

With only enough equipment for two more time jumps, the
travelers prepare to jump again before they get caught up in the
conflict. Too late—the team is attacked and captured, and soon they find
themselves amid an extraordinary society of spider-worshipping
Neanderthals.

Lincoln and Skyra, although from two very different
worlds, deepen their unusual bond as they become embroiled in a daring
plan to launch a revolution. In the midst of turmoil and deceit, they
make a new friend—who may embody their future destiny.
