Girl, Forgotten (William Morrow) “Girl, Forgotten,” by Karin Slaughter (William Morrow) Andrea Oliver, a newly minted U.S. marshal, is assigned to protect an aging Longbill Beach judge who’s received death threats. But the real reason for the assignment is to prove that Clay Morrow, a vicious killer who happens to be Oliver’s father, murdered a pregnant girl 40 years earlier. As readers of Slaughter’s “Pieces of Her” know, the jailed father is threatening Oliver and her mother.
