Fantasy novels are my favorite kind of books, and they are a rich source for poetry that reminds us of the magic in the world. This one is from The Once and Future King, by T. H. White.
When we get to an oak
which was struck by lightning in the year of the great storm,
we shall meet at a rendezvous there.
Afterward we shall have to move like shadows.
We can't come nearer.
From that moment you will have to go alone.
In the days of flint,
before iron was ever invented,
The uncomfortable feeling.
with an iron knife-blade hidden close to your hands,
will be safe,
so long as you do not let go of it.
All you will have to do
is walk the last distance.
