Hello Always-Maybe,
I found Melody Beattie's writing style very welcoming. I read the book, then I turned around and read it with a highlighter. Not every chapter applied to me, but in fact I was thinking I should re-read it now that I am now a year + down the road...
I really like her daily reader too called Language of Letting Go. I first got it from my library but soon bought my own copy. I carried it everywhere for a year.
