Yes! You should definitely continue, it gets really good! I agree, the beginning can drag on a bit, but trust me, you would regret not finishing it!
I've read all three books numerous times <3
What size are the microsoft word pages? If it's the regular 8x11 or something (which is the size of a piece of printer paper) try switching it to 5.83 x 8.27 which would be the size of a book, then see how many pages you have :]
30 pages really isn't that much, even the smallest childrens book...
If the book is in third person, is it okay for the prologue to be in first? I kind of want it to be like a letter to the reader, in a way. My story is set in the future, so I was planning on making the prologue be a letter written to the past by my main character saying how things are much...
