I've read a decent amount of thought provoking non-fiction recently and felt in the mood to change to something quite the opposite. Was thinking of novels that are more formulaic, easy to sink into, and generally aren't that thought provoking.
Some things i've read before that give this feeling for me:
Agatha Christie's Poirot novels and some of the Inspector Gamache novels
Jack Reacher novels from Lee Child
Legends & Lattes by Travis Baldree
