Everything the reviewers in the one star category have written is unfortunately true. This book is a mess. It needs a thorough reworking with a good editor because it does have the basis of a sound plot. Readers are not interested in long meetings about banking mores involving characters who make fleeting appearances, add nothing to the plot, then disappear. It's like watching paint dry and is called padding, or waffle. Similarly, descriptions of places ideal for a travelogue but where the reader visits little and wishes to revisit less.
I gave up half way through.
My advice is to withdraw this book, do a thorough professional rewrite, edit then re-publish under a different title.
