Sexual abuse (ie: rape) is an aspect present in several of my books, though it is always in retrospect–never explicit, but either implied or a partial memory that is obscured (being attacked and knowing where it *may* lead but never actually witnessing anything that goes beyond assault and into sexual assault, if that makes sense) . Some of my books have themes where substance abuse is involved (ie, alcoholism)–some but not many. Also–suicide is an undertone/plot aspect in FALLOUT.
