After searching a while for the first title I tried the second one (as the plural authors made me question my results).

Did you mean: "Difficult Conversations: How to Discuss What Matters Most" by Douglas Stone, Sheila Heen, et al.? and: "Thanks for the Feedback: The Science and Art of Receiving Feedback Well" by the same authors?

Not the original commenter. Difficult Conversations is a great book for understanding the dynamics of communications. It has a lot of overlap with the NVC book, but it's very poor in terms of giving actionable advice. The NVC book has the opposite problem: Great in terms of giving actionable advice, but poor in explaining the "why" behind the advice.
