My boyfriend is getting married. Okay, technically he's my ex-boyfriend. Two months ago, he decided he wanted a break. I still thought he was my happily ever after. On any other day, knowing he was gone for good would be the worst thing that could possibly happen. But not today. Because not only is my boyfriend getting married, his bride is my best friend. And they've sent me an invitation.

I live my life by a few simple rules—let no one in, trust only my family, and don’t ever spend more than three nights with a woman. Those are easy enough to abide by until I meet gorgeous, captivating, and absolutely brilliant Sophie Winston and fall into a dangerous romance with the sister of the detective investigating my father’s murder.

He's my brother's best friend... And completely out of bounds... One look from Nathan Davenport makes my heart stutter. Six feet three inches of pure muscle with stormy blue eyes that see right through me. He's everything I've dreamed about since I was sixteen. And snuck glances as he trained with my brother in our backyard. Not that he noticed... He’s the decorated Royal Marine who commands every room he enters. I'm the curvy girl who hides behind textbooks and oversized hoodies. He’s the definition of off-limits–my brother's best friend,...

At work, I’m King of Wall Street. I’m shrewd. Exacting. Some say ruthless. At home, I’m a single dad trying to keep his fourteen-year-old daughter a kid for as long as possible. And nothing I say is ever right. When Harper Jayne starts as a junior researcher at my firm, the barriers between my worlds begin to dissolve. Soon, she will have to learn that I don't just rule the boardroom. I’m in charge of the bedroom, too.

As a scruffy, disorganised daydreamer, Lucy Mayweather is like a fish out of water at the high-powered offices of her brother’s billionaire best friend. When she agreed to work for Felix, she had no idea quite how cut-throat his world–or he–would be. She just wanted to escape her reclusive life and be close to her childhood crush, hoping he might notice her. But Lucy’s lonelier in London than she’s even been in her tiny village back home.
