The more promising title is Helen Bond's The First Biography of Jesus: Genre and Meaning in Mark's Gospel (due in April), a focused analysis of Mark as a Biography. For Bond, the issue is how to understand what Mark is saying and also what Mark is doing. I'm anticipating a great leap forward, building on Richard Burridge. I also note gleefully that Bond's ToC eschews "plot" in favor of "structure," which is a far more appropriate description for the storyline of a biographical narrative.
Incidentally, this is something the early narrative critics completely overlooked, which explains why some efforts to discern a single "plot" for each Gospel amounted to creative mash-ups of various thematic elements (e.g., Powell, Moloney). That later narrative critics stopped focusing on Plot (amidst the explosion of interest around studies of Character) may indicate that they had found some awareness of this. The Gospels don't have plots, per se. OF COURSE THEY DON'T. They are Biographies.
On that note, I do hope Keener and/or Bond might mention something about the episodic nature of biographical narrative, specifically in refuting the old "pearls on a string" criticism, which would have been equally absurd if levied against Suetonius or Plutarch. Reliability or truthiness of content aside, if one should not judge a fish on its ability to climb trees, then one should not assess ancient bioi by the qualities of Aristotelian tragedy.
Without specific regard to the Gospels, I wrote about plots versus biographical storylines in the series I called Remembering Life Stories:
