The New York Times bestselling memoir, which has received widespread acclaim, deals with the author's struggle to understand her mental disorder and sheds light on this often misunderstood and stigmatized mental illness.

A sociopath is not a psychopath. That is a completely different disorder. It cannot be reduced to simply being an antisocial person.

I'm sharing my story because it reveals a truth no one wants to admit: that evil lurks in the last place you'd expect. I'm a criminal with no record. I'm a master of disguise. I've never been arrested. I've rarely felt remorse. I'm friendly. I'm responsible. I'm invisible. I blend easily into those around me.

Do you think you know someone who's a sociopath? I bet you do. But I also bet they'd be the last person you'd suspect. Contrary to popular belief, sociopaths can't be reduced to their personality traits. They're children seeking understanding. They're patients hoping for recognition. They're parents yearning for answers. They're human beings in need of empathy.

But the system fails them. Schools don't recognize them. Professionals don't treat them. And they literally have no one to turn to for help.

I am a 21st-century sociopath. I wrote this book because I am certain that there are others like me.
