It's too unrealistic; it's like this perfect fantasy where you end up with a happily-ever-after ending and a BFF as a queen. I agree with Adrian: she ended up with a happily-ever-after ending at what expense? What happened to Eddie? What about Jill's mom? Sonya? She gets people to help her; then Dimitri just tells her to leave them alone and work out their problems by themselves? That's what a friend is? I felt like she used them. Did she even have to sacrifice anything for her friends? 
 But then, it's the fairy-tale type of story that kind of makes me like it. 
 So what makes it a fairy tale? 
 -Rose always ends up alive, 
 -Lyssia ends up queen (I mean, what else would you have expected?), 
 -(view spoiler)[the bond is gone, 
 -Tatiana dies - totally *perfect* solution, btw - how else would everything else work out so perfectly? (hide spoiler)] 
 And that's what happens: it's too perfect. It's still a pretty good series; if you're looking for a dose of reality, you just won't find it here. 
 It's really nice though, if you want to just kick back and relax and find yourself in a bubble of fantasy.
