A slow burn with excellent stakes - Lee and Annie could be called star-crossed but that would lessen the seriousness of their situation. Lee is of the noble dragonborn, a secret he must keep post-revolution, and Annie is from the poorest of the poor, which means she's discriminated against not just as a female dragon rider but because the old class system lingers. As children, both saw their families ritualistically murdered by the other side and it's absolutely horrifying. As young adults and soldiers, they are required to make life or death decisions and realize there are rarely easy answers. At times I found the pacing slow but the payoff was absolutely worth the wait, I will definitely look for book two.
