Honestly, most modern books on Stoicism read like that; I tend to avoid them altogether. Although I will say that Donald Robertson has done a great job with the two books I've read of his (Stoicism and the Art of Happiness, How to Think Like a Roman Emperor).

The best modern book, in my opinion, is Pierre Hadot's The Inner Citadel. It's primarily about Marcus Aurelius' Meditations, but does a really good deep-dive into Stoicism (and frequently mentions other Stoics).
