In the 21st century, the majority of the world's population are Therapied model citizens. But there seems to be a slow unwinding, becoming ever faster as old mental illnesses return to haunt people long cured. In differing ways, both Mary Choy, policewoman, and Martin Burke, therapist, become involved in this strange event. Choy and Burke, last seen in Greg Bear's Queen of Angels, have since moved on: she now works in Seattle, he is a freelance therapist, his earlier, grandiose plans in tatters. And through the myriad people they deal with, they begin to understand the possible terrors this new mental plague could unleash... Greg Bear is one of the word's best - and bestselling - science fiction writers. Slant is a towering achievement from a writer at the height of his powers.
