A love story for all time, Dark Fire: Yesterday's Tears begins with a chance encounter between Jane Garrison, an elite fighter who has been grievously wounded in combat, and Edan Duff, the young entrepreneur and creator of marvelous devices, whose genius will save her but turn her into the mystery woman who calls herself Sim. Although left powerless to quench his yearning, an unbreakable bond forms between them. But Edan knows it is a bond that must be broken if Sim is to be restored to a normal life, and that he must live with the pain their parting will cause him. Yet another chance encounter—is it really chance?—unites them once more, this time against a distrustful US government and a power-hungry President bent on making sure that only he can a distrustful US government and a power-hungry President bent on making sure that only he can exploit Edan's most astounding creation yet. Dark Fire: Yesterday's Tears takes Edan and Sim through worlds both familiar and as-yet unknown as they struggle to live out a love transcending time and fate.
