Return Billionaire to Sender: A grumpy hero - opposites attract romantic comedy (Billionaires of Manhattan)

I may be a shy, lowly letter carrier, but when my beloved apartment building is threatened by a mysterious and reclusive billionaire, I’m willing to push the envelope. I’m going to march right up to Malcolm Blackberg’s fortress of fierceness and deliver a cease-and-desist notice he can’t refuse. Except as soon as I get inside his gilded doors, things go sideways—I’m mistaken for Malcolm’s court-ordered emotional IQ coach, as if I’m acting out a wacky postal carrier cosplay. They drag me in, a sacrificial lamb for the big bad. Make that big, smolderingly sexy bad. So I make up a lesson involving a story about our building. He doesn’t seem happy. Can he tell that I have no idea what I'm doing?Before I know it I’m flying around the country, up close and personality testing the most devilishly exasperating man I’ve ever met. He’s scary for sure…but the way he sometimes looks at me turns my knees to jelly, and has me writing love letters to his gorgeous eyes, his mouthwatering smile, his impressive…package. Our coaching sessions are getting hot-hot-hot, but I can’t let my guard down. If he ever finds out I’m a first-class fake, I’ll lose everything I’ve ever loved in this world!
