Jeff Shaara has switched venues in his new novel To the Last Man:
... the endless dialogue between the action sequences is a chore, heavy on exposition and light on character development.
Sounds like he wants to teach history. Not that the desire to entertain is completely forgotten:
For all the overwrought prose, the exploding skies, the guts that "twist into a hot swirl," the throbbing hands, deafening roars and straining skulls, the horrors of the western front never really jump out at the reader.
I hate when that happens.
