Sharing a summer house with a hot-as-hell roommate should be a dream come true, right? Not when it’s Justin…the only person I’d ever loved…who now hates me. When my grandmother died and left me half of the house on Aquidneck Island, there was a catch: the other half would go to the boy she helped raise. The same boy who turned into the teenager whose heart I broke years ago.

Rule number one for dating your best friend’s sister: Don’t. Just don’t do it. Especially when your best friend is dead and the last thing he made you promise him was that you’d keep an eye on his little sister, but not too good of an eye.

The beginning of my sophomore year in college was off to a rough start. On the first day of orientation, I had an altercation with an infuriating British dude in a campus bathroom. (The ladies’ room was out of order. So, I used the men’s room. Don’t judge.) I got home later that night and realized that the foreign student we were expecting to rent a room in my parents’ house was allergic to our cat. So, the spare room went to someone else: Caleb - the British guy from the men’s room. And so it began...my love-hate story with Caleb Yates. Or was it hate-love in that order?

It started out like any other Tuesday. I spent 12 hours writing algorithms for one of the largest companies in the world and then came home to work on a pet project of mine—feeding facts about the men I knew into a formula to find my perfect match before my twenties came barreling to a close.

It all started with an unexpected phone call. Two years after my fiancé passed away in an accident, his father died suddenly, leaving Brad’s adult special-needs brother with no one to care for him. The next thing I knew, I was on a cross-country drive to New Hampshire where I’d be moving in to look after Scottie until I could get him into a group home. The last thing I ever expected? I wouldn’t be taking care of him alone.

When my grandmother found out she didn’t have long to live, she embarked on a crazy trip—jumping out of airplanes and scuba diving with sharks. After I repeatedly voiced my concern, Gram blocked me—her own grandson—on text and social media, leaving me only her travel companion Eleanor’s number.

The day I showed up to Dax Moody’s sprawling home, I had no idea what was coming. As a traveling massage therapist, I was used to entering the houses of strangers. But this assignment was different from any before it. From the outside, I’d correctly assumed the owner was rich. What I didn’t realize was that he would be younger than I’d imagined, single, stunningly gorgeous, and mysterious.

I was a small-town girl with big city dreams and more ambition than money to my name. He had everything—money, privilege, and the world at his feet. Opposites in every way, but that didn’t matter. We were lightning in a bottle, and everything felt possible when we were together. Life was perfect.

They called him Mack Daddy. No, seriously, his name was Mack. Short for Mackenzie. Thus, the nickname. Perfect, right? So was he: perfect. The perfect physical male specimen. At the private school where I taught, Mack Morrison was the only man around in a sea of women.

It seemed like a good idea at the time. Look up Landon Roderick, that boy from childhood whom I'd never been able to forget - even though he so easily forgot about me - and call him. Then again, anything sounds like a good idea when you've had a little too much wine before bed, right? It was supposed to be just a quick, meaningless prank call. Instead I went off on him - unloading 13 years of pent-up emotions. I didn't think he'd call me back.

For the last year, I’ve wanted someone I can’t have. The man my father built his latest multimillion-dollar business with. He’s nearly a decade older than I am, and he’s entirely forbidden. The fact that he’s never given me a second glance only makes me long for him more.

The first time I met Caine West was in a bar. He noticed me looking his way and mistakenly read my scowling as checking him out. When he attempted to talk to me, I set him straight -- telling him what I thought of his lying, cheating, egomaniacal ass. You see, the gorgeous jerk had wined and dined my best friend-smooth talking her into his bed, all along failing to mention that he was married. He deserved every bit of my tongue-lashing and more for what he'd done.

It was the summer of my life. I’d met the guy of my dreams. Unfortunately, he was the son of my uppity employer - and very much off-limits. But Gavin was a rebel. He knew his mother would disown him if she found out about us; in his eyes, we just had to be careful. He never treated me as his mother did - like hired help. Instead, Gavin put me on a pedestal and loved me harder than I’d ever been loved in my life.

Growing up, the three of us were friends. He was the nerd. I was the playboy. She was the beauty. Deep down, I only ever wanted her. I kept it inside because Rory and I made a pact that our friend, Amber, was off-limits. He lied. I went off to college, and he got the girl. Amber never knew how I felt. They were together for years - before he broke her heart. Through it all and across the miles, she and I casually stayed in touch. When my job sent me to Boston for a three-month contract position, Amber let me stay in her spare room.

Reasons why I should not be drawn to Troy Serrano. Number one: He’s obnoxious. Number two: We were enemies more than a decade ago. Number three: He’s my friend’s ex-boyfriend. I could go on and on, really. When my boss gives me an unwanted assignment, and tells me it involves spending time with the grandson of one of our residents, the grandson turns out to be Troy. Lucky me. Four hours a week of having to deal with his insufferable personality and unsolicited advice - the only consolation is getting to stare at his annoyingly gorgeous face, in between our many arguments.
