Time Siege, a fast-paced time-travel adventure from award-winning
author Wesley Chu.
Having been haunted by the past and enslaved by the present, James
Griffin-Mars is taking control of the future. Earth is a toxic, sparsely
inhabited wasteland - the perfect hiding place for a fugitive
ex-chronman to hide from the authorities. James has allies, scientists
he rescued from previous centuries: Elise Kim, who believes she can
renew Earth, given time; Grace Priestly, the venerated inventor of time
travel herself; Levin, James's mentor and former pursuer, now disgraced;
and the Elfreth, a population of downtrodden humans who want desperately
to believe that James and his friends will heal their ailing home world.
James also has enemies. They include the full military might of
benighted solar system ruled by corporate greed and a desperate fear of
what James will do next. At the forefront of their efforts to stop him
is Kuo, the ruthless security head, who wants James's head on a pike and
will stop at nothing to obtain it.
