STEP 2. Look through the books that are similar to your book project. Just read the blurb.
STEP 3. After you are finished with shaking your head and thinking 90% of them sound like predictable/ boring / unbelievable / rehashed premises.
STEP 4. Think that through once more.

STEP 7. Keep writing your book.
