Jacky Farber series

Being a huge fan of Patrick O'Brian, who wrote a series on the Royal Navy in the early 1800's,  I was delighted when one of my writers group authors, Stephanie Jacob Gordon, shoved a book in my hand to read:  Bloody Jack: Being an Account of the Curious Adventures of Mary "Jacky" Farber, ship's boy.  This is a fabulous four book series about a girl who is mistakenly taken as a boy to serve in the Royal Navy.  Love, love, love these books.   I highly recommend them.  At one time I had all four, but they left the house borrowed never to return.  I will have to either track down the people who have them or hie myself back to the bookstore. I really want to read them all again!
