Hans Urs von Balthasar is one of the great Catholic theologians of the 20th century, and Thomas Aquinas one of the great theologians of the Middle Ages.

There were a few contested points I wish he had addressed, but as someone with a fondness for both thinkers, I was generally pleased. The book might even be a solid intro to Balthasar
