A Knight of the Seven Kingdoms (The Tales of Dunk and Egg, #1-3)
I only read the first two, mostly because of library due date pressure.
But I didn't see enough in the book to justify waiting and getting it out again. Dunk and Egg are pretty good characters, but the stories were largely forgettable. They mostly seemed to be fan service, dropping house names from the main series of books so the reader can squee over them.
So, diverting, but eminently skippable.
