I usually give out book recommendations based on the person's interest. So I'll give my best shot for making a generic recommendation.
The first thing to understand is that books on meditation are not going to help you all that much. This is not something you try to understand intellectually. It is experiential. You are much better off attempting to practice. If you need help with practice, there are various groups and flavors of mindfulness meditation: vipassana, zen, insight, etc. There's going to be a flavor, and a group of people with whom it will feel right.
Barring that, hacker_9's suggestion of the Meditation sub-reddit is not bad. My suggestion though is to ignore the people talking about theory -- practice, find people who practice, and allow the issues and observations to surface up from there. It's a kind of empirical inquiry into yourself where you drive the discussion through your observations, rather than the other way around.
Now having said that, the most generic book on helping you practice meditation that I recommend is Mindfulness in Plain English. You can find this for free online.
I have also heard about Calm and Headspace apps and knew people who tried it. They are probably not a bad way to start -- though like all things, it comes and goes, and there will come a time to drop it and move on.
Traditional Buddhist teachings don't necessarily get into the psychological aspects of it. Or let me be more precise: the psychological descriptions don't seem to resonate well with Westerners, and is typically dismissed as part of empty ceremonies, or pre-modern descriptions of psychology. (For example: what does the Padme Family or the element of Air have anything to do with your day-to-day life?)
So a meditation practice can be paired with therapy, and will work very well if the therapist also practices.
That leads to the other book I would recommend, since people are interested in healing their neurotic patterns. There is a great book whose technique complements mindfulness meditation: Tsultrim Allione's "Feeding Your Demons: Ancient Wisdom for Resolving Inner Conflict". This book distilled out an older practice in a way that combines with gestalt therapy and presented in a way that is much more accessible for people who grew up in the West. Like the tradition it comes from, although the full method uses visualization methods, it ends with mindfulness meditation. Along with a regular practice of meditation, it's a great way to deliberately gain some insight into your subconscious.
Hope that helps.
