I liked the book and enjoy the movie based on it a lot as you can tell.
Lyrics
When they come we’ll be ready to fight
Backs to each other brothers in the night
Raise your sword run your enemy through
Fight or die it is the best you can do
Riding through the mist coming in waves
They have no interest in plunder or slaves
Defeated foes will surrender their heads
Mountain of bones tribute to the dead
Come my little brother we have fences to build
We must be ready or we all will be killed
There is no mercy for of them it is said
From the mist will come the eaters of the dead
Down from the mountains on their horses they ride
A dragon breathing fire with steel for his hide
Desiring human kind to feed and to slay
We will be lucky if we live out the day
She says that we should take the battle to them
To find the mother deep within her den
Slay the mother and the leader as well
We must destroy them in the cave where they dwell
Come my little brother we have fences to build
We must be ready or we all will be killed
There is no mercy for of them it is said
From the mist will come the eaters of the dead
One is dead but still another remains
They will not flee until their leader is slain
If there is fog tonight again they will come
It will continue until the battle is won
Behold he rides upon the head of the beast
The dragon brings him to the table to feast
Upon his head the horns of power reside
And many others upon horses do ride
