Throne of Jade is a very different novel from its predecessor, being one of exploration and adventure rather than the Age of Sail / black powder army combat that formed the basis for His Majesty's Dragon. If you were expecting Napoleonic squares augmented by fire-breathing dragons, you will be disappointed, and I think the lower rating reflects these dashed expectations. However, I was drawn by Temeraire's and Captain Lawrence's relationship and that core idea is executed wonderfully as they travel to China.

I am delighted by the expansion of this alternate history as we see what China looks like given the inclusion of these intelligent dragons. Naomi Novik cleverly weaves China's traditional dragon-heavy culture into a society that is strikingly modern and egalitarian. She captures the fundamental dynamics of China and Britain's political relationship during that era, though only on the edges as this novel is ultimately about dragons. The peek into the world-building -- of society, cultural values, and even economics -- is executed brilliantly and I enjoyed the months-long journey to Beijing.

I'm glad I stuck with this, since the former novel left me wanting. Recommended.
