A portal ripped open, thrusting me into a strange new world. And then, I met her. I must return to my guard post at once, but she ignites a fire in me strong enough to threaten the sacred vow I've made to protect the Crown.

Meet three passionate couples with off-the-charts sparks.

Mia Lorenzo wasn’t exactly my top choice for a wife. She is 14 years younger, a hopeless romantic, and in line to become the head of the family that just orchestrated my father’s murder. Too bad my father's dying wish was for me to marry Luca Lorenzo's daughter. I will unite the two families for my father’s sake, even if it’s just to find proof that they killed him. The only problem is my brand-new wife. That auburn hair, those bright blue eyes, and the way my gut twists whenever I see another man go near her.

Carrie might be lost, but she's exactly where she needs to be—in the big tattooed arms of a hot possessive mountain man. This obsessive alpha knows how to treat a city girl right!

I have always been the good girl. The quiet girl. And I’m sick of it. I want to play; I want to have some fun. And there is one man with whom I want to do that. Caleb Anderson.

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?

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.

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.

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....
