One wedding. One reluctant bodyguard. One dangerously inconvenient attraction…

Penelope Lee didn’t want a new bodyguard, especially not a brooding, battle-hardened vampire who would rather be anywhere else. But when her assigned protector is murdered just before her sister’s wedding, she’s left with no choice.

Enter Dahlia St Clair, commander of the vampire-hunter army and the last person who should be stuck on glorified babysitting duty. She’s there to drink, dance, and maybe cause a little trouble—not to shadow a bratty princess through a wedding filled with secrets and unseen threats.

But when danger strikes, and Penelope becomes a target, Dahlia is the only one standing between her and death.

One stolen moment turns into another. One brush of hands, one heated glance, and suddenly, duty feels a lot more like desire.

They both know the deal: once the wedding is over, so is this.

But when the final toast is made and the vows are spoken, they’ll have to decide—was it just a moment in time, or the start of something worth fighting for?
