Scene versus Summary--Which to Use for What Effect

I like picking up what I call "airport reads," just to see what's up in commercial fiction.  Airport reads are those books that airport bookstalls buy, thinking they'll take travelers' minds off flying.  It's a big coup to get your book in an airport bookstall, and over the years, I've seen more serious fiction arrive on those shelves.

Recently, I got a copy of JoJo Moyes' new book, After You.  Her novel, Me before You, a story of a woman caretaker for a paraplegic who helps him with assisted suicide, was made into a movie, and I enjoyed it a lot--good characters, tense situation.  Moyes is a master wordsmith, expertly pacing her stories.  After You is the sequel, as you may have imagined, and it also starts with a bang--the main character falls off a roof and has to return home to her parents while she heals.
