Seth Loveless has been my weakness since I was sixteen years old.

Two years ago, I moved back to my hometown. I started a business, bought a house, took up yoga, and went on hiatus from dating. Life is good.

If I never had to see Seth, it would be perfect.

After all, my history with my ex-boyfriend is anything but simple. It's taken us years, but we've finally learned to live in the same town without killing each other.

Is there an elaborate set of rules governing our every casual interaction?

Yes.

Do I still think dirty, off-limits thoughts every single time I see him buying apples at the grocery store?

Of course. I'm only human, and Seth and I are practically experts at the two F's: fighting, and...

...sleeping together.

Still, we're managing just fine.

And then?

He shows up at my sister's wedding. The man looks like pure sex in a suit, handsome as the devil himself and twice as charming.

Worse, he claims he's my date.

We flirt.

We dance.

We break every one of our carefully-crafted rules, and we... should stop.

Too bad I'm having the time of my life.

I know I should end it. After all the heartbreak, hurt, and anger we can't be more than enemies.

But Seth asks me for one more night.

Just one night.

Then, we're back to being virtual strangers to each other.

I know I should turn him down.

I know this ends with my heart shattered into a million pieces.

I know lunacy is doing the same thing over and over and expecting different results.

But I've always been bad at resisting a weakness.
