"Another exciting and explosive tale of ambition, ingenuity,
intrigue, and discovery. Against the Tide of Years is even
more compelling than Island in the Sea of Time-but just as
much fun." - Jane Lindskold, author of When the Gods Are
"Amazingly real. The research is impeccable, the writing excellent." - Harry Turtledove
