Rule number one: Hands off my kid sister's best friend.
Rule number two: See rule number one.
Rule number three: Seriously, don’t even think about touching Luna.
Luna is my new roommate. My very off-limits roommate. My gorgeous, feisty, painfully tempting roommate.
I try to keep my distance. To ignore her soft laugh, her intense eyes, her sweet smile. And that groan, the one she makes over her morning coffee.
All right, the sassy college student is driving me out of my mind.
I can still keep my hands off her. I double down on my rules. Draw that line between friends and lovers. Then, she kisses me. And, suddenly, it’s obvious. There's no way in hell I can resist her.
The Rule Breaker is a stand-alone best friend's brother romance with a feisty college student heroine, a brooding tattoo artist hero, and enough heat to melt your earphones. Come see why fans say "no one writes broken bad boys like Crystal Kaswell".
