I pull my phone out of my jacket pocket and text Layla the news that we’re no longer going to The Chambers. Then I check my emails. I’m scrolling through the usual marketing ones when I spot what looks like a very sophisticated phishing scam. It’s an email with my name as the sender. I’m about to delete it but then I spot the subject line and it sends shivers up my spine: Note to My Future Self.

It can’t be.

I click open and hold my breath.
