Royal Rescue

The concept of this book is really cool: a fantasy world where royals have to choose if they want to be a rescuer or rescuee, then go on quests to find a spouse, but what happens when an aroace prince with no intention of marrying anyone comes of age and changes the system?
The book itself is disappointing. Most of the characters weren't very likable or fleshed out, the plot changed directions too many times and a lot of it ended up happening “off screen”. I think it could have worked better as a short story.
