Finally, because the clock in the wall showed they were running out of time, Margo a few conclusive notes before she would stand and hand in the sheet of paper to the professor's desk:
Maybe my mistake in this runes string is giving importance to two edges, two points of interest. For one, we have the secret, fire and protection. Even with only these three runes I would have problems determining the actual order of the runes in the string. (If we are thinking it from English Grammatica, we would need finding what the charm is protecting and then the source of harm from which we need protection (the fire); so we miss a noun in between. And you can't protect the "revealing of secrets", it doesn't sound coherent. On the other hand, we have Love and Luck, that is, luck at love. Grammatically speaking, Dagaz would be before Gifu. So a last possible order for the runes would be 


= Algiz+Dagaz+Gifu+Kenaz+Pertho:: "Protect Luck at Love against Fire & the Revealing of Secrets. It would change the meaning but it would appear to be the most coherent alternative from them all. At least in Grammatical English.
