Imma give 3 out of 5 stars but it might go down to 2. 
 Let me just say that I am absolutely heartbroken because the first two books were like my favourite and 5 stars but this book, this boook is so disappointing, because of that bloody ending. it was not good at all! Why did she have to pull that bulls***? 
 Also, I expected a bit more from the villan, from Kelsea, from the Red Queen. I just expected more okay? 
 Please Erika, please re-write this book, I'm begging you. :'(((((( 
 PROS: 
 - The characters like Mace and Pen, I really liked him hahah 
 - New character, Katie is cool. 
 - Kelsea's and the Red Queen's friendship 
 - Kelsea's and The Mace friendship 
 CONS: 
 - THE WTF ENDING. 
 - Fetch, I expected more. 
 - Finding out Kelsea's father. It was shocking but I expected more. 
 - World-building, I feel like things more explained well. 
 - The Red Queen 
 - Row and his 'children' 
 Overall, I am so disappointed and heartbroken with the ending IDK what to do. I loved the first two books. but oh god. WHYYYY? 
 SPOILERS BELOW 
 (view spoiler)[ 
 WHY DID ERIKA CHOSE THAT SHITTY ENDING? WHY? So in the end, there's no Tearling? Like I feel it negates all the hardwork Kelsea had done and suffered. And I did not understand how it all happened. So Lilly came out of Katie's mouth and killed Jonathan and Row? And? I don't understand. So now Kelsea is a normal girl, no longer Queen. And everything is back to normal, like in our technology kind of world. I am super heartbroken. 
 AND WHEN SHE MET THE NEW WORLD PEN, IT'S SO HEARTBREAKING. So no one remembers her? I am okay with her not ending up with Pen, but I kinda wish it was done in a better way. 
 I wished that she saved her original world. Like Erika could've used another alternative man! For me and my own au ending, Kelsea will break her forgiveness to Row, and managed to kill Row with her Sapphires, but the consequence is she would lose her life. Like before she dies, she should make a document to break the monarchy and place a democratic ruler or something. Then Aisa would have joined Caden, Pen would be heartbroken but will heal. Like they would build a new world. But oh well, this is Erika's book. 
 And wtf The Red Queen died like that? I mean, I loved the growing friendship between the two, but I wished like the Red Queen betrayed Kelsea? Because she's evil ish. Or at least use her dying breath to kill Row. 
 AND I DON'T UNDERSTAND HOW ROW MADE HIS CHILDREN? And they became so strong they killed everyone? Idk man. Ugh, Kelsea could've used her Sapphires or something. So she used up her Sapphire powers? 
 And Mhurn is her father? Goddamn. It was shocking but I was expecting more. Like a better, more shocking alternative that could explain why she can wield the necklace? IDK man.I just, ugh. 
 And Fetch is Gavin Murphy from the past? Eh. Like when we learned about him from Katie, he was so yucks and my impression of him just went down man, down to the ground. 
 UGH IM SO SAD LAH. IM SO SAD. 
 (hide spoiler)] 
 What a unsatisfying ending to a beautiful trilogy. Such potential wasted. So heartbroken. Would I recommend this series? Only the first two books.
