Once Upon A Marigold (Upon a Marigold #1

the long version

Christian was clueless when he started spying on the royal family through his telescope. He lives in a cave with a troll for a dad, after all. If his dad had only warned him about all that mind-boggling love stuff, maybe things wouldn't be such a mess. Although then, maybe, Princess Marigold would be dead. But Christian wasn't warned. And now that he's fallen for the princess, it's up to him to untwist an odd love triangle--er, rectangle--and foil a scheming queen who wants to take over the kingdom, even if it means bumping off her own daughter.
