Force Unknown

In the dark,
In the cold,
A heart,
With a crust of stone.
Strong so it may take forever and a day,
To reach the warmth below,
But weak enough that it takes just one blow,
One force to shatter the stone,
A blast of passion,
Causing a heatwave of heart and mind,
Riding on winds so high,
Then crashing low,
Crushing heart,
As it did stone.
In the dark,
In the cold,
A heart,
Destroyed,
By a force unknown.
