Hey, thanks for the follow. ^^ I took a quick peek at your book and it sounds good. Problem is, Twattpad is fickle and decides based on looks and descriptions. Your first paragraph has AMAZING descriptions, but if it doesn't have a blurb. At all. I've never seen that before and I've been on this website 8 years!
If you struggle finding a good book cover, there are plenty of graphic designers who work on Twattpad and can provide amazing covers for a very small exposure fee of a vote or comment on their story. As for the blurb, you need to write SOMETHING. Even if it's something as simple as, this book is about dragons and bananas. If you provide a summary, in depth or only a brief paragraph, I can help make it more engaging, if you want.
Don't let your descriptions go to waste. It's very rare to find work as engaging as yours. :)
