What I'm most interested in as a reader are two simple things.
1) A story that engages, captivates.
2) A writer with not only 'style', but a distinct voice.
This novel has both. (Although, to be honest, 'Good to a Fault' is less a 'story', than a 'situation'.)
The premise is compelling. The characters are all so nicely drawn. (I HATED Clayton.) The pacing is measured, but not unduly so, with some absolutely memorable moments. And Ms. Endicott has a way with language that put a smile on this writer's face.
Having just read an absolute piece of dreck ('The Memory Keeper's Daughter'), I was relieved to have my faith in the possibilities of good writing restored.
