Sounds like you'll definitely like TWISTED TRIANGLE, and if you like true murder stories involving former military, then you may also want to try BODY PARTS, which is coming out in March. It's about serial killer Wayne Adam Ford, a former Marine, who killed four women (that we know of) and dismembered two of them. It's not a gory gruesome book because I don't write books I wouldn't want to read. I took a more psychological angle.
Re: the addiction theme in NAKED ADDICTION, many of the characters have different addictions, ranging from alcohol to meth to cocaine to cigarettes, caffeine, sex and damaged women. You'll see that the drugs also play into the murders. Don't want to give anything else away.
Let me know what you think of this and the other books if you decide to get them. My email is crother@flash.net.
