Daine and Numair are facing what is certainly their doom when they are pulled into The Divine Realms by none other than Daine's parents, whose are both lesser gods. Though it is a very tearful reunion for Daine and her mother (who, when still mortal, was murdered by bandits) Daine and Numair must return to the Mortal Realms to help Tortall in her fight against Ozorne, who is back--this time as a conniving Stormwing instead of a conniving emperor, and with plenty of mortal and Immortal allies.
Since the war in the Mortal Realms is going on at the same time as a war between The Greater Gods and the Queen of Chaos (Ozorne+ Chaos=cohorts? Yes.), none of the Gods can be bothered to help Numair and Daine get back home, so the two are forced to make the perilous trip across the Divine Realms to request help from the Dragons. They also discover that they love each other--a wonderfully tender note in an otherwise plot-driven novel.
Once transported back to the Mortal Realms (courtesy of the Dragons), Daine takes on Ozorne in a bloody, decisive battle that ends the fighting in both the Mortal and Divine Realms.
The Realm Of The Gods provides a very fitting end to the series, and quite a satisfying one as well. Though quite fast-paced, the story is still imbued with detail and with enough character development that it doesn't rely completely upon plot. Though the trek through the Divine Realms got a tad monotonous at times, Pierce navigates the story well and does a good job of bringing the series to a fulfilling conclusion.
Rating: 13+ (violence, mild cursing, romance)
