In my Heir of Dragons series there is some descriptive of self-harm, my Legacy of Dragons series has some instances of physical abuse. The Savage Wilds series has an implied instance of rape.
Most of my books have characters who have undergone some traumatic experience and have emerged stronger because of it. The Savage Wilds series has probably the most on-page violence level, but nothing too extreme.
