I always end up recommending the same books over and over again on Twitter, Facebook and in real life to adults with similar reading habits to me! This will be a working post where I'll collect the absolute best of the best of them. Each image will take you to the Amazon page for that book which has a synopsis - generally I read them on Kindle when they reach a reasonable price. All of these books are in the psychological thriller/crime genre and are generally quite fast-paced and gripping. Most were recommended to me by friends and others were recommended by Amazon (which seems to know my preferred genre pretty well by now!).
