Good books almost always have good covers.
But does that mean that a good cover will make a good book?
Of course, it doesn't.
But in many situations in life we act as if it does.
We get fooled by the people who want to sell us the "cover".
Because we like to get fooled.
We take the shortcut.
Because we like taking shortcuts.
The shortcut that every book has a good cover and that a good cover will consequently make a good book.
Unfortunately, it doesn't.
What makes a good book is a good writer...
