I have had a long time interest in Hellenistic Philosophy. I admire the Epicureans, the Stoics, and the Sceptics. Over the last few years, I have read several to learn more about them. I looked forward to reading A. A. Long's survey of Hellenistic Philosophy for some time. So, I was highly disappointed when I found it nearly unreadable.
I am sure that for someone with more technical knowledge of philosophy this book is an excellent overview of Hellenistic Philosophy. However, I don't have that technical knowledge. I was looking for a book written for the lay audience. Hellenistic Philosophy is not that book. So, unless you are ready for a slog through a dizzying array of technical topics on Hellenistic philosophy, find another book to read.
