Greta and the Goblin King is set in the world of Mylena where the humans are considered evil and where every kind of creature from faeries to goblins to gnomes, demons and ghouls thrive. But Agramon wreaked havoc on Mylena and the Great Mother had to put a curse of ice and snow and the two moons on the people of Mylena. The world-building is flawless and being as taken with the icy cold weather as I am, I found myself wanting to feel the cold penetrate deep in my bones more than once. 
 Add up all that with a human stuck in their world unwillingly as a result of a sacrifice to save her brother's life. Suffice it to say that it hasn't been an easy four years in Mylena for Greta. But Luke miraculously didn't kill her on sight, instead took her in and taught her all the trades of surviving. Everything was as peachy as it could be for Greta when the goblin king decided to pay her a visit during her job as a bounty hunter. The same goblin who just a fortnight ago was trying to get her to say his name and unknowingly giving him the power to come inside her mind whenever she dreams. All because Greta intrigued him. Now isn't that charming. 
 What do you do become when you have nothing? Fearless is only a glimpse into Greta's personality and she is pretty self-reliant. But for a human to survive right along with paranormal creatures as a bounty hunter and trying to disguise her humaneness. Not an easy one. But somehow Greta manages until all hell in the shape and name of Agramon threatens to take her last bit of her sanity. 
 And then there is Isaac, the infuriatingly intense and hot as hell Goblin King of Mylena. Only not as much by choice but as a stroke of fate. It is so engaging to see Isaac hot on her trail, haunting her in her dreams, making her want him and trying to get her to see the real him. But Greta haven't earned the title of the best bounty hunter for nothing. She is an expert when it comes to guarding her emotions. Only lately, along with Isaac, she is somehow also letting others affect her judgement and making her care. 
 Wyatt, Sloane, Jacob and especially Ray made me fall in love with their stories and it was admirable to see them trying to protect each other through thick and thin. All of them played a role in trying Greta to see the other side of the story and to light the fire in her again that willed her to live and survive in the cold, cursed land of Mylena.
