Welcome.
We are big fans of Dr. Austin's book. I personally think it is the most-accessible, user-friendly introduction to Epicurus's philosophy currently available.
We also have two episodes of the podcast where we interviewed her, 156 & 157

Does it faithfully represent the authentic Epicurean view ?
Yes, and she does a masterful job of dispelling from some of the misconceptions like Epicurus's supposedly being an ascetic. Her adherence to the actual texts is well done without being pedantic.
