My thoughts: It truly is a great book and an easy read. It will not answer every question one might have about Catholicism, but it's also only just over 200 pages. I do recommend "Why We're Catholic" to anyone wanting to learn some basics of Catholicism including Catholics like recent converts or Catholics that may not know much about many of the topics that I listed that the book covers. If you have a family member or friend that converted to Catholicism, you may want to read this book to gain some basic understanding of Catholicism especially if you are struggling with their decision.
Trent Horn does have several other books like "The Case for Catholicism: Answers to Classic and Contemporary Protestant Objections" which is 342 page and "Hard Sayings: A Catholic Approach to Answering Bible Difficulties" which is 435 pages. Although I own both of these books, I have not read either of them. However, knowing Trent's style, they are both great books.
