What if one day you woke to find all your draft emails had been sent? (Including that one love declaration meant for your ex-boyfriend - the only man you've ever loved . . .)

Three years ago, when receptionist Millie Chandler had her heart broken in a very public way, she became a closed book, vowing to keep everything to herself - her feelings, her truths, even her dreams. It's safer that way. There's less chance of her getting hurt.

But Millie does have an outlet: her draft emails. Sarcastic replies to her rude, tactless boss, pleas to friends she wishes would be better, rants in response to bad service, and of course, that five-hundred-word love declaration to Owen, who, three years on, is about to marry someone else. She never sends them. Never would. They live in her drafts, where nobody can read them and nobody gets hurt - especially, not her.

But after a server outage at work, Millie wakes up on a normal-seeming Wednesday morning to find that all of her emails have been sent. Every. Single. One.

As every truth, secret and darkest thought she's worked so hard to keep password protected are catapulted out into the open, Millie must fix the chaos her words have caused, and face everything she's ever swept under the carpet.

Will Millie find the strength to finally open both her heart, and her inbox?
