I have to admit, high fantasy isn't really my thing. I tend to try and steer clear of it as much as possible, mainly because there's something in my brain that can't compute with all the fantastical terms and creatures. However for some reason, I was keen to read Greta and the Goblin King, and my interest definitely paid off - this was one fantasy read I thoroughly enjoyed.Greta and the Goblin King starts off by jumping straight into the action and doesn't stop. Fast paced and very thrilling left me never wanting to finish, which is a really good thing!I have to admit that it took me a while to warm up to Greta as a character. I didn't really click with her like I usually do with other female leads, and I almost wished that she wasn't so horrible to Isaac. Her distrust of him seemed understandable at first, but as she continually refused to have anything to do with him - without little explanation, got old quickly. And it's not like Isaac was horrible to her or anything - in fact, he was properly one of the sweetest guys I've ever met. Charming, seductive, aloof...Isaac was amazing. I completely fell for him. Which I guess was half the problem...because even after a secret is revealed, you just want to love him.The world building was done really well also. I enjoyed reading about Mylenea and how it came to be, how humans are considered the enemy, and there are all sorts of creatures that co-exist, some not so harminously with each other, ruled by different kings in different counties. I would have been interesting to know more about those counties, but there's only so much you can cram into a novel!While the ending seemed to happen too fast for my liking, enough was left open for the second novel, which I can't wait for. This was a really captivating novel that left me in a daze - mainly thanks to the amazing Isaac who has just earnt a spot on the top of my YA Boys to Watch Out For. He will make you swoon like anything!
