This book was recommended to me by my sister and we have two copies of it on our bookshelf. My husband and I have both taken the test and written our strengths in the inside book jacket.
We've compared our strengths, which are very different than one another. In fact, we don't have any overlapping ones, which was a conversation in itself. When you buy this book it comes with access to an online test which gives you a report at the end. The book chapters detail each strength.
If you like self-help books, leadership and management theories, and psychology, get this book. I loved it.
