Erin’s older sister has gotten a new job at a posh hotel in a wealthy coastal town. She’s excited to move there and leave the past behind. Unfortunately, the past decides to follow them in the form of her sister’s sleazy ex-boyfriend, Graham. Erin has never liked him (with good reason) and has always gone out of her way to avoid him. So when her sister caves and takes him back, Erin gives her an ultimatum: him or me. Sadly, she chooses Graham, leaving Erin with nowhere to live. While visiting her sister’s work to drop off her key, she discovers some forgotten storage space in the attic of the hotel. It’s a perfect spot to hide out, full of unused furniture where she can lay low until she finds somewhere else to stay. And it all goes swimmingly until the hotel owner’s son discovers her one day. Erin is humiliated, because this boy isn’t a stranger. Tristan Balfe goes to her school. He’s one of the most popular students and the star rugby player. Erin expects Tristan to tell her to leave, but instead he promises to keep her secret, so long as he can hang out with her from time to time to eat junk food and watch reality tv shows. Erin readily agrees and a friendship blossoms between them. Still, Erin knows she needs to move on at some point. She can’t freeload forever and she doesn’t belong in Tristan’s world. However, when the time comes to leave she doesn’t have the courage to tell him and flees without a word of goodbye. Tristan is left wondering whatever happened to the girl who captured his heart for a few short weeks during his last year of school. A Quiet Promise is a novella of the Quiet Love series and is a prequel to Tristan's full-length book, Beneath the Quiet Sky (Quiet Love #5).
