When it comes to criminal, author wise I can recommend Leena Lehtolainen and Taavi Soininvaara, those are my favourites right at the moment. They have plenty of books with stories that aren´t too obvious with their storylines and outcomes, so you can´t really guess what comes up on the next pages (that´s a reason why I dropped Dan Brown´s book because it became boring pretty fast...)...
"Deborah Spungen: And I Don't Want to Live This Life: A Mother's Story of Her Daughter's Murder" is quite a story, interesting but also at times, hm, hard to read in the sense that it is touching but creepy at the same time...but it´s cool, I can only recommend that book. That book is written with the help of the mother of the girl that was murdered, but at times it seems pretty surreal that it really is supposed to have happened XD
Anyways, "Touched with Fire - Manic-depressive illness and the artistic temperament" by Kay Redfield Jamison is a great book, but going very into detail when it comes to the psychological aspects, what you could already guess from the title...
