Materia Oscura

Jason Dessen was knocked unconscious and kidnapped before he wakes up surrounded by strangers in hazmat suits. "Welcome back," they say. This world he's woken up to is not the one he knows. His wife is not his wife. His son was never born. And Jason is not a physics professor at the university... Is this world a dream? Or was his world before the dream? To find out who he really is, Jason must face the darkest parts of himself as he battles a terrifying, seemingly unbeatable foe. Dark Matter is a brilliantly plotted tale that is at once sweeping and intimate, mind-bendingly strange and profoundly human--a relentlessly surprising science-fiction thriller about how far we'll go to claim the lives we dream of.
