Write a science fiction ebook

I am looking for a talented writer to construct an engaging and original science fiction ebook, with a length of 200 pages. I'm particularly interested in exploring the sub-genre of Biological Science Fiction, with no specific plot or storyline in mind - I'm open to suggestions. If you believe you have the skills it takes to create an exciting and imaginative book, then I'd like to hear from you. The book should be clearly readable in all types of devices. The book should be maximum 5 mb. The format should preferably be .docx.
