Books

Hey y’all I am new here so nice to meet y’all! I have been obsessed with the show for so long now, and I want to start to get back into reading. And the main books I want to read is the ‘You’ series. I was looking on Amazon to order the books and I cannot for the life of me figure out which order they go in. Also are the books worth it? And are they drastic changes from the show?
