Why was Michael Crichton my most read author from 2012 until last week?

For almost 5 years (2011-2016) Michael Crichton was my most read novelist. He is now tied with Stephen King at 18 books. When I'll finish reading Gerald's Game, in less than a week, S. King will be my most read author at 19 books.

It was September 1993, two months after the release of the film: Jurassic Park; and it was my first day at primary school and I saw a student holding a book about dinosaurs, with Jurassic Park's logo on it. Since then I wanted to find this book so bad. Almost 20 years later (2011) after watching the movies dozens of times, I managed to read the book along with its sequel The Lost World. Then I discovered that M. Crichton wrote a variety of books, (historical, legal, aliens, fantasy, technology, environmental, crime, Victorian, pirates e.t.c)

So I started reading book after book until I read all of his books with the exception of his John Lange books and his non-fiction ones. Unfortunately he died in 2008 so I won't read any more from him.
But that won't stop me from (re)reading his novels again and again. Ah! Ah! Ah! It won't stop me.
