Desperate to find this phonics book

    Hello teachers

    I am a mother of two and my oldest started
    kindergarten last week. Her pre-k teacher
    told me about this book set a few months
    ago that I absolutely HAVE to get for my
    daughter! Unfortunately she is now on
    maternity leave and I can't reach her. I
    obviously am kicking myself now for not
    having searched for the when she first
    mentioned them. I will attempt to describe
    them as I was told. PLEASE help if you can
    identify them...

    To my best summation I'd call them phonics
    books. There is one about "ph" and "f" and
    one about "ow" and one about silent "k". The
    letters as it was described to me are
    characters in the books. For example in the
    "ph" and "f" book, the f argues with ph that
    it's a fraud kind of thing. Like the ph is
    impersonating the f.

    If this sounds familiar to anyone please let
    me know the name of the series and/or
    author. My daughter and I would be ever so
    grateful! Thank you!
