I thank everyone for commenting because it means a lot to me that my stuff gets read! So, thank you.
To your question, yes, that was on purpose; the idea was you weren't supposed to know a sense of time, a sense of what was real or not real, what was happening and what was imaginary because the character doesn't know. So, switching up tenses seemed to be a unique way of screwing up time.
First off, your book cover is very interesting. The fact that it's not some simple picture really grabs my attentions.
Ok, now to the text.
When I started reading, I was immediately caught. A great start! However, after I flipped the page, you seemed to continually change from past to present-tense. Was that on purpose?
But other than that, I didn't want it to end! Great job!
