14 learning calc does anyone know if this books any good ?

I finished 9th grade, and i was bored during the summer, I saw a calculus book at the library it's an introduction to calculus by hugh neill I bought it like a week and 5 days ago, and I just finished the differentiation chapter, does anyone have any reviews about this book ? I looked mostly everywhere online and found nothing about it, I'm asking because my understanding felt a bit shaky, and the examples weren't that clear to me, so if anyone has tried this book out please tell me about it

And if anyone has any recommendations about learning calculus, I'm definitely open
