Fury of the Kings by Lacey Carter Andersen

I made a thoughtless decision, then I lost my princes…

Apparently, the best time to ask someone a life or death question is when they’re fresh from being kidnapped and tired as hell. Who knew?
Now, my princes are gone to a terrible place, and it’s up to me to bring them back. To do so, not only do I need to learn to survive in a new world of darkness and lies, but I need to decide how I feel and what I want for my life.
Rescuing the princes is only the first step. Agreeing to turn this fake marriage into a real one is the next, if I can handle it. And then? Well, I need to figure out if I can be the wife to four men tricked by a potion.
