hi Im looking for a tonks/potter story not sure what its called but from what I can remember of it, tonks meets a man who helps her train harry up to fight, I think he's a squib, harry and tonks get together and the man is like a brother to them both, I remember that the man had something to do with dementors, harry gets injured and tonks pretends to be harry while fighting.
like I said cant remember what it was called but its driving me crazy tryting to remember so I can re read it, any help would be much appreciated
