It was a total power fantasy kind of book with the heroine being just all sorts of kick ass and trumping everyone in the story, but it was well done and fun!
The reason why it lost a star for me was because the military training dragged on too much for me at times and also MY OT3 S O BS.
No, really, the heroine was a great character although the beginning was a bit eye-rolling with how stubborn and prickly both she and the male lead were. But once they acknowledged their feelings for each other halfway through then it was smooth sailing.
Oh, another reason why this rates so highly for me is because Ao Tian IS THE BEST SECOND MALE LEAD EVER. I'm so devastated at how we don't get a resolution for him and he's just been silently protecting and helping the heroine since the beginning. Ugh, my heart.
