In my opinion, for a first course in Latin, it is one of if not the best books. Collar and Daniels is another solid choice. Lingua Latina is the best if you are learning in a classroom. What this book is so good at is, if you are like me learning solo, it’s a self contained course. It doesn’t need any extra instruction. Another bonus is how it gets you ready to read de bello gallico. In my opinion, the faster you get out there reading real Latin the better.
