Every volume in the Caribbeancom library aims for a different "vibe," and Vol.123 leans heavily into the trope. Here is what sets it apart:
Sofia thought deeply, her mind racing with possibilities. And then, a smile lit up her face. "The answer is a promise," she said confidently. Luna was impressed. "A promise is indeed something that can be broken but never held. It is something that can be given but never sold. You are wise beyond your years, Princess Sofia."
