Looking for Books on attachment theory

[Pinkgin22]

That’s it really. I was wondering if any of the lovely posters here had any personal recommendations of books that have helped them in real life?

I use attachment theory a lot at work, but I found David Howe's Attachment Across the Life Course easy to understand how attachment affects us at different ages. There's also a book about schema therapy (which is a combination of different theories and therapies including attachment) called Reinventing Your Life by Jeffrey Young that's very interesting.

Avoidant: How to Love (or Leave) a Dismissive Partner by Jeb Kinnison. Very good, helped me understand XH.

Also Women Who Love Too Much is based on women with anxious attachment.

Thank you so much for your replies
