Sundials Hidden books lyrics

If I was a Leo, this would be so perfect.
But I've got these bullhorns and they always fit.
If I was a Cancer, I would be my best friend.
Don't you know you're one of them?
If I was an author, I'd write a book in space.
I mean in the context, not in my working place.
But if I was published, we'd all be in the stars.
We'd be constellations sharing our common parts.
Like the books under my coat

That Douglas Adams wrote,
I won't read you for a while, but you've always made me smile.
Hidden beneath me under a pile of clothes,
I'm missing the planets that I had grown to know.
But if I could find you I wouldn't know where to start.
If you're not what I remembered your pages could break my heart.
With two heads connected, your memory escapes me.
