I'm afraid that this is one of those cases where a book's blurb discourages me from looking at the book itself.
The blurb you write is the very first example anyone will have of your writing. If it's poorly written and filled with mistakes in grammar, punctuation, etc., this does not give a very good impression of what the book itself might be like.
But in spite of this I took a look at the preview.
Are you paying your editor? I hope not, because if they told you your book is ready they're wrong. In just the very first paragraph there is, among other things, a comma missing after California and "Cavalier" is uncapitalized. After finding more than a dozen things that needed correction on the first page alone, I was not anxious to look further.
Every book, even the most professional, have mistakes...but you have far too many in too short a space. You really need to get someone to go over your text for you.
