2.0 stars, with a lot of goodwill. Nope, scratch that. No goodwill for this one. 
 Actually, I was about to rate it with four stars and would have done so, had I not read the last thirteen chapters. It is going to be a hard exercise trying to explain my feelings about this story without spoiling everything (which is a difficult task, as "Tyrant" is very plot-oriented), but I will give it a try. Minor spoilers which may say something about the direction this story is heading towards are included nevertheless, so if you plan to read this story, please don't read on now if you want to be completely surprised. 
 Basically, T.M. Frazier wrote a triangle romance (geez!) with some standard twists thrown in to make things more interesting. During the first 70% of the story, this procedure worked (for me). The characters felt real. Doe was a protagonist to root for. There were funny pieces of dialogue, relationships explored in all their depths, characters written in a relatable way. The author's concept of love which was established in this story was questionable, though. The I-fell-in-love-with-the-man-who-kidnapped-handcuffed-and-threatened-to-rape-me-kind of love was valued above the We-are-childhood-friends-with-a-deep-connection-and-plans-to-get-married-kind of love. And then there was this *he-betrayed-me-so-I-wanted-to-leave-him-but-then-we-had-sex-and-everything-was-fine-again* scene. Supported by King's unbearable "You are mine!" or "I own you!" exclaims, this perfectly sums up how the author defined this relationship through their sexual attraction. 
 Doe had a lot more chemistry with Tanner during their honest conversations and common scenes with each other than Doe and King could ever have had. I actually hoped Doe and Tanner would get their happy-end, not because I wanted Doe to return to the life before her memory loss, but because Tanner was the guy who would do everything for her - just like King would - without constraining her freedom - which is what King did. So, what would an author who wants her protagonists to end up with each other do? Indeed, throw in new revelations in order to make King, the man who seems to favor murder and rape as ordinary hobbies, look like the good guy. From then on, everything went downhill in this story: The scenes were rushed, important aspects were just skipped, the characterizations became poorly performed, and the writing didn't improve either. I even skimmed the last few pages because I was rolling my eyes permanently. 
 As to the writing itself, T.M. Frazier is talented indeed, but it was not dazzling. And she needs a capable editor; instantly! Someone has to teach her about how to use apostrophes and quotation marks correctly. 
 This genre, it seems more and more, just is not meant to be for me. I keep being disappointed by this kind of stories, and I cannot bear yet another story on the bad boy turning good because of his princess who does not mind him being a murderer, rapist, thief or whatever. The "King" series was not bad in its entirety, to be honest - the plot and the characters were well-developed; I never felt bored reading about them. Even the minor characters were elaborate and interesting. But sometimes, this is simply not enough.
