Historical Novels Review of Workhouse Orphans

I have just read a very snooty review of my book in the magazine of the Historical Novel Society. The critic begins by saying that this is not the sort of book she normally reads and, after damning with faint praise for most of the article, concludes that it is an enjoyable read and would probably appeal to those who like sagas and ‘rags to riches’ stories. Since this is exactly the brief I received from the publisher I guess that means it is a success. It ‘does what it says on the tin’!
But it does beg the question, why give a book to be reviewed by someone who does not understand the genre? All the reviewers in the magazine are amateurs and books are allocated by editors who deal with the work of a particular publisher. Couldn’t he have found someone who enjoys that kind or book?
As a consolation, the book continues to receive 5 star ratings on Amazon.
