This book is violent.  Torture is a feature. I did like it though.  The beginning was slow, but when it hooked me, I was interested until the end.  You have to lean into the suspension of disbelief and let go of your knowledge of science but I've granted that to lesser stories. This is a story that toys with our idea of God.  What happens if he died? It's interesting and despite the horror, unlikable characters and unbelievable science there is something almost charming about it.  The mystery keeps you engaged and then it's hope that sustains you. This book is not for everyone but most assuredly for some.
