Biochemical evolution and the origin of life Book

Please only read Katie Fforde in the summer and two years apart. She can write at a good pace, the plots are ok, the settings great - the Cotswolds. Some of the author's ethical decisions are admirable. In Grace the restoration of the gardens, the mockery of the millionaire and model terrific, the resolution just right -- but too much like a lemon souffle. I think there's an old word that applies 'air headed' -- Not terrrible, but surfacey. I'm not being crabby, I enjoyed Restoring Grace, just demanding more from writers and readers.
