Tvarex

Zach Day remembers how the world ends.

When aliens turn Earth into the board for their ancient and merciless game, humanity's last hope is a teenager with memories from a doomed future.  With knowledge acquired from fifty years in the future, Zach Day must secretly rebuild the Project Necessity team, accelerate human technology, and reshape history. 

But the L'lark are on Earth and watching.  If they discover what Project Necessity is doing, they'll erase humanity forever.

If Zach fails, Tvar will proceed and in the last phase reset life itself.

Tvarex is a fast-paced saga of survival, innovation, and the opening moves in a secret battle for Earth's fate.
