LAP17796, while everything Dr. Drib said is important - you should follow his advice - I must add: some successful, published books (including some bestsellers) have been written by poor grammarians who've had an interesting story to tell, the help of a strong editorial team, and sometimes, a ghostwriter. So, if you believe in your story, then don't be discouraged by the work required to get it told.

As a first step, I suggest that you enroll yourself in one or more writing workshops, where you'll receive feedback and advice from the moderator and other members, as well as learn what works well and what doesn't from reviewing/discussing other members' work and the already-published works recommended and discussed. In the USA, where I live, public libraries, some bookstores, arts councils, and local colleges (especially lifelong learning programs and community colleges) often host high-quality writers' workshops free of charge or for a nominal fee. You might also ask your local librarians, booksellers, and English teachers for help locating suitable workshops and writing classes.

Good luck!
