I read this for academic purposes, otherwise, I would not be reading it. I say that because I obviously prefer reading fiction, as opposed to academic textbooks.
However, this textbook was informative and detailed for the course I am undertaking. Despite that, there were some sentences, more than a few, that made me want to pull my brain out my nose because the grammar was painful to endure. Regardless, this textbook helped me understand the basics and foundation of computer security, which was what I needed.
And yes, I did need to reference it in an essay, annoyingly. But anyways, did we expect anything else?
