Meet Eva, who can’t feel pain, and Anna, who can’t escape it.   Everyone has heard about the case of Eva Reid. Ever since she was born, she’s been immune to physical pain – she can get a paper cut, break a limb, and even give birth without feeling a single thing. Her rare condition has long-captivated reporters and researchers – including Dr. Nate Reid, Eva’s husband and acclaimed scientist renowned for his work in The Pain Laboratory. Also among them is Anna Tate, a ruthless journalist with a dark past of her own.   When Eva is suddenly found dead inside her home, it raises a flurry of questions around the last night of her life – and who might’ve been involved. Anna finds herself growing increasingly obsessed with Eva’s case: her cloistered, painless existence, her promising career as a psychotherapist, and especially her toxic relationship to Dr. Reid, whom she met and married as his former patient.
