Locked up

I'm all locked up
and protected.
You can't get to me here,
I'm much to far away.
You want my heart,
you want my love
well that's not going to happen.
I have walls of stone,
and gates of steel.
Electric fences and
a thousand  bloodthirsty tigers
protecting my heart.
Ive got the world's most feared serial
killers as my my body guards
and fifty plus assassins surrounding it.
I have trenches a mile deep,
that you have to cross and
black fire in a tight ring
surrounding an invisible box
with no lid.
That box is where my heart lies
and where my love lays dying.
If you can get there, great
for you.
But by the time you get that close
I'll be gone, far away
and in hiding
with my heart in an invisible box.
