A Driftnet catches everything. A teenager is found strangled and mutilated in a Glasgow flat. Leaving her warm bed and lover in the middle of the night to take forensic samples from the body, Rhona MacLeod soon recognises the likeness between herself and the dead boy and is horrified to think that he might be the son she gave up for adoption seventeen years before. Amidst the turmoil of her own love life and consumed by guilt from her past, Rhona sets out to find both the boy's killer and her own son. But the powerful men who use the Internet to trawl for vulnerable boys have nothing to lose and everything to gain by Rhona MacLeod's death.
