The writing style is OK (though a little confusing, what with the mixture of first, second, and third person narration), but there's a lot missing here. Newton's not a very interesting person to write about, and Stott doesn't do the scientist any justice in this novel. The modern-day characters seem a little bit flat, and Lydia Brooke, for all her intelligence, doesn't quite "get" things, even when they're laid right before her eyes! In all, this book was an admirable effort, but not something I'd recommend. Try Diane Setterfield's The Thirteenth Tale instead.
