This book fundamentally relies on two things: spirituality and generalisation. Unfortunately, they do not do it any favours.
It's my fault, really. I bought The Truth About Love on a whim, and I must have missed the part of the blurb that explains that this is first and foremost a spiritual book. I was trying to motivate myself to read more non fiction, and since I have a tendency to gravitate toward heavy themes when I do, I intentionally chose this book, knowing it would be on the lighter side. That part, at least, turned out to be true. Other than that, I expected discussions of different aspects of love and assumed they would strongly rely on anecdotes from the author's life. What I got instead is a discussion of the concept of love as a whole. Different chapters do highlight slightly different aspects of it, but because they are all based on the author's perception of spirituality (which is not a bad one, just not one that I share), they are ultimately very repetitive. Anecdotes are sprinkled in frequently, but they are so short that they do not contribute much. The one thing I really enjoyed is the author's style -- the quick pacing, the light-heartedness, the easy, entertaining way with words. And ultimately, this is why I will withhold a rating: The book is well-written. I am just not the target audience for it.
