Blood and Blue

....Welp, continuing on from the last two books, here we are again at the start where Shadow faces a battle between two ponies that she knows V E R Y well from her past.
Will she be able to beat them?
What about her friends?
What about the ponies in her visions?
What about the visions?

....Is it the future, or the past that she is living in?
Or maybe, just maybe, the past and future collide with the present.
