Yes, you should certainly buy it. Especially if you love the lore in Elder Scrolls. Most people who are unhappy with the events that take place are simply ignorant* of the fact that those events were already foretold in the lore of the previous games. Especially when you consider it's under $10 how can you not buy it!?
However... without spoiling I'll say it's kind of like half a book really. Super cliffhanger. So, you might just want to wait until the sequel book comes out and buy them both. It's supposedly coming out on the 27th of September, but that's only from a amazon listing. We've had no official confirmation so far.
*I'm not using ignorant as an attack, but as what the word actually means. Ignorant = 2. Lacking knowledge, information, or awareness about something in particular.
Just thought I should clarify that. As some people take offense to that word :shrug:
