Harleigh Wren Maguire has loved Phoenix Wilder for as long as she can remember.

He's everything she isn't.

Brave.
Reckless.
One-hundred percent unapologetic.

But it's Halloween... the perfect excuse to dress up and be someone you're not. To step out of your comfort zone and do things you wouldn't usually do.

And Harleigh is determined to make her best friend notice her for once.

There's only one problem.

Everyone knows monsters come out to play on All Hallows' Eve...

She just didn't ever think Nix would become her worst nightmare.
