I agree with @wolflu66 - I feel it's too dark to understand what's going on, or to catch the readers' attention. Increasing the contrast is a great idea, or even trying with a flat background with no texture.
I'd also change the font to something that fits the "vibe" of your story (is it terror? is it fantasy?). A good font for your title can go a long way! - I'd also try to center it and make it bigger so it's easy to read. Maybe make the "Book 1" part a subtitle in a smaller size, to highlight the story's title!
