This special edition includes an interview with Erin Morgenstern about how she invented her circus.
 
The circus arrives without warning. It is simply there, when yesterday it was not. Against the grey sky the towering tents are striped black and white. A sign hanging upon iron gates reads:

Opens at Nightfall
Closes at Dawn

As dusk shifts to twilight, tiny lights begin to flicker all over the tents, as though the whole circus is covered in fireflies. When the tents are aglow, sparkling against the night sky, the sign lights up:

Le Cirque des Rêves
The Circus of Dreams

The gates shudder and unlock, seemingly by their own volition.
They swing outward, inviting the crowd inside.

Now the circus is open.
Now you may enter.
