Does anyone know any books or anything about what it's like to go through schizophrenia?

My friend had a freakout a few years ago and got locked in psych jail for a week and diagnosed. They put them on anti psychotics which helped but now it's gotten worse and meds aren't working.

I find myself spending a lot of time wondering what it's like for them, but I can tell they aren't comfortable talking about it too much and I don't want to pressure them just for my own curiosity.

There's lots of info out there but so much of it is dry clinical/medical stuff. Does anyone know any good writings about what the experience is like? What the voices are like, how it effects people to live through it, stuff like that.

Thanks.
