"Aquinas" by Fesser

I've finished reading Edward Feser's "Aquinas, a Beginner's Guild." The book ends delightfully:

For Aquinas, we are not here for ourselves, but for the glory of God, and precisely because this is the end set for us by nature, it is in him alone that we can find our true happiness. And it must be emphasized that [] he takes this conclusion to be a matter, not of faith, but of reason itself.

Therein lies the sting of Aquinas's challenge to modernity.

Yes, I'd recommend this book to anyone embarking on trying to understand St. Thomas's work.
