The most interesting part of this book is the essays by people who knew Lewis. Those make it somewhat worth reading. The rest of the book is essays, mostly about his non-Narnia works and his Christian philosophy. While those could have been interesting, they tend to be worshipful. This doesn’t mean that they are bad or un-informed. They are quite good, but the essays do not deal with any negative aspect of the work. The closest you get is an oft quote from JRRT and then a comment about how we shouldn’t judge him for it.
