iOS 10 by Tutorials Subscriber Access

I am currently a subscriber for the past 9 months. I currently have free access to the book iOS 10 by Tutorials because of this. Due to some financial difficulties if I cancel the subscription for a few months will I still be able to access this book in my loot section or do I have to purchase it? Will I be able to easily continue my video subscription again after a few months? Thanks a lot for all your awesome tutorials they are really useful for me. Great work team.
