I was never supposed to fall in love with my stepbrother. I never intended to. It just sort of happened. Rule number four - You can change your mind, too, Ethan. We can't. We're done. This girl lives in the same house as me. Her bedroom is just down the hall. It barely takes 20 seconds to go from her room to mine, and yet it's an impossible distance now. She might as well be on the sun.

This is bad. Very bad. He's rubbing off on me. Resident bad boy Ethan Colton is turning me into an irresponsible bad girl. Rule number two: When I tell you to come here, you come here. It's still an order, still practically growling at me, commanding me to obey him, but it's more, too. It's fun and flirty, a little playful. I can see why girls fall for him, can see why his devious smirk melts their resistance, because it's doing the same to me.

How can something so wrong be so perfect at the same time? Rule number five - I'm going to show you some things that you'll never forget. It's wrong. Not just this, but everything. I knew it was wrong, but I thought I could get away with it. Why, though? I'm not like this. I'm good. I'm the good girl, the girl with perfect grades, the girl who does everything right, prim and proper. I don't cause trouble, I don't get into trouble, I don't....

I don't know when it happened. I didn't think it'd ever happen. I can't lose her. I can't even imagine losing her. Rule number six: This is supposed to be fun. Understand? He's my bad boy and I'm his good girl. And, yes, he's my stepbrother and I'm his stepsister.

Rule number one - It's only supposed to last for a week.... Ethan is a cocky, arrogant jerk. He's always been that way. I'll never understand why girls trip over themselves just to be with him. Don't they realize he's going to ditch them in a week?

We all have our strengths and weakness. We're all good at something and bad at something else. This is why we need each other. This is why it makes sense for Ethan and me to be together. I'm the good girl, the careful, cautious one who thinks before she acts. Ethan is the bad boy, the risk taker, the person who jumps into action regardless of the consequences. Sometimes you can't wait to think before you act, though. Sometimes you can't be careful or cautious.

Rule # 12: You can tease me, Ethan, and we can play, but you can't be mean to me. I need to know that there's more, that this isn't wrong, that you feel the same way I feel.... I never wanted to hide this from you, Dad. It wasn't about that. It wasn't that I was ashamed or thought I was doing anything wrong, but I didn't think you'd understand, and I wanted to be with Ashley. I want to keep being with her, and whenever I thought about telling you and then thought about you getting mad about it...well, yeah, that's it.

Ethan's been avoiding his stepsister since their parents got married, but when she shows up at his apartment uninvited, he realizes her absence has only made his heart grow fonder....

Keeping up a perfect good-girl image is hard for Allie Hall, especially when her stepbrother is the notorious Jace Harbor. With her head always buried in her books and the haunting memories of her father’s death, she wants nothing more than to end senior year on a high note, so she can get out of her shitty town. Jace Harbor can’t wait for graduation. He’s tired of the liars, cheaters, and football groupies at Redwood Academy. When his father forces him to spend a week alone with Allie, he remembers that part of Redwood that isn’t all that bad.

The headline says it all, and my bosses are over the moon when the opportunity of a lifetime lands in my lap. Of course, they aren’t aware that I’ve already met Vince Cool at an all-star gala—and that we were at each other’s throats the entire time.

I’m a full time single dad. A former NFL player turned coach, tasked with turning around a college team full of kids who either don’t take it seriously or are determined to get injured. I will absolutely not be falling for my new neighbor.

I should have known I was in trouble when I backed my old, beat-up truck into the shiny Range Rover. The driver looked like a gorgeous fallen angel–one who’d been booted right out of paradise for being a giant prick. Good thing I’ll never have to see him again.

It's not every day your dean is a 6'4" dark god with ocean-blue eyes and a dimple. Just looking at him makes my heart pound and my stomach flutter. He's intense, filthy, and forbidden. Not to mention, he's my sister's ex-boyfriend. If I were smart, I'd walk away. Lines are getting blurred. Boundaries are being tested. And rules are about to be broken.

He was my dad's best friend - and my first crush. Falling for him was bad. Flirting with him and trying to get in his pants the night of my 21st birthday party was definitely worse. But can you blame me? I hadn't seen the guy in years and he comes back looking hotter than ever. Our fling shouldn't have even begun but now that it has, I don't want it to stop. I'm crazy for this guy - and he's obsessed with me. Too bad my father will kill him if he finds out. So we can't tell him. We just have to keep it secret. Right? That might have worked...until he got me pregnant.

Everyone says opposites attract. And they must be right, because there’s no logical reason why I’m so drawn to Colin Fitzgerald. I don’t usually go for tattoo-covered, video-gaming, hockey-playing nerd-jocks who think I’m flighty and superficial. His narrow view of me is the first strike against him. It doesn’t help that he’s buddy-buddy with my brother. And that his best friend has a crush on me. And that I just moved in with them. Oh, did I not mention we’re roommates?

Why am I dating this girl? I'm supposed to be the one teasing her and getting what I want. It's not supposed to be the other way around. I'll give her what she wants when I'm good and ready to do it. That's how this used to work. She's changed the rules completely.

Boyce: I was a broken man trying to heal. She was my daughter’s best friend. Strictly off limits...until that one night, when she looked...all grown up. Vivian: The day I lost my parents changed everything. Thankfully, I found a soft place to land. But when I grew up and moved away, I couldn’t get him out of my head. Now, I’m all grown up, he’s single, and we’re both willing.
