Review in full from Publishers Weekly, 2015:

“In prose sometimes as elegant as a gold and glass airship, or as stark as a dragon destroying an entire city, the worlds Deas carefully built in his previous Memories of Flames novels are slowly torn apart. Bellepheros, Grand Master of the alchemists’ Order of the Scales, is kidnapped by Taiytakei slavers so their sea lords can exploit his control over immortal dragons. They need a dragon rider, so they capture the fallen dragon queen Zafir. The Taiytakei have also enslaved Tuuran, former soldier in the Adamantine Order that answered to Zafir, and Berren the Crowntaker, a warrior cast into another’s body through sorcery. Bellepheros is charmed by the compassionate witch Chay-Liang into building a dragon eyrie, Berren seeks to undo his curse with the help of Tuuran’s skills and companionship, and revenge-bent Zafir swears to destroy all Taiytakei everywhere with her dragon, Diamond Eye. All of them race toward a major clash that may appear in future books but is only hinted at in this installment. Deas’s dense tale unfurls a fantastic multiverse where a queen can become a slave but a slave can change worlds.”

It’s been a while since I got excited by a review, but for Publishers Weekly I make an exception.
