The impression is fresh for a while. What is the first thing you do?
Do you discuss it? Do you write some kind of review for yourself? Do you explore professional reviews/analyses instead to compare the perspectives? Do you give yourself some time to form an opinion? Do you do something else?
Most of the times I start my next audiobook right away. But there are times when the old story and characters linger in my mind. Those I read reviews on Goodreads and research on the book and the author. Even if I don’t do those things, I still can’t move on to the next book just yet. I listen to music until my mind is ready for a new story.
