The Realms of the Gods

Daine and the mage Numair are faced with certain death when they are suddenly swept into the mystical realms of the gods, where Daine learns the secrets of her past. But she and Numair are both needed in the mortal world to help fight the desperate war that is raging in Tortall. And so they undertake the journey home – a dangerous journey that will teach them about life and about each other. Their path leads them to the final clash, which involves both gods and immortals – a battle in which the only chance for Tortall's future lies with Daine and her wild magic.

Set in Tortall during the reign of King Jonathan IV and Queen Thayet, Realms of the Gods is the final book in The Immortals series, which chronicles a time when the world is invaded by immortal creatures.

In this final book of Daine's story, she and Numair are teleported to the Divine Realms. Daine's mother, Sarra, is now the Green Lady, a minor goddess of healing and childbirth in the northern provinces. Although it has been hinted at before, Daine's father is revealed in this book as none other than the minor Northern God of the Hunt, Weiryn. Despite her happiness at being reunited with her long dead mother, Daine and Numair know that they must return home.

However, getting into the realm of the gods is much easier than getting out, so, aided by the badger god and the god of platypi, Daine and Numair must travel a very perilous road to the dragons, to petition them for help in getting back to the city of Tortall.

It is revealed during their journey that Numair Salmalin harbors very strong feelings for Daine, though she had not believed it to be anything serious. After saving her life from spidrens, Numair forgets himself and kisses Daine, admitting he loves her very much. Daine also loves him, but the two have doubts about a lasting relationship because of their age difference; Daine is sixteen, and Numair is twenty-seven (as quoted by Tamora Pierce through interview).

They go through many perils to reach the Dragonlands, where two dragons agree to bring them back to the mortal realms. Once they reach their destination, they see that Tortall is being attacked. In this fight, Daine defeats Emperor Ozorne of Carthak. Daine then has to decide whether to stay in the mortal realms as a mortal or live in the Divine Realms as a minor goddess with her mother and father. After discussing this with Sarra and Weiryn, she decides her true home is the mortal realm. Her mother promises to visit when she can.

Numair asks Daine to marry him in the epilogue of the book. Daine does not agree immediately, but it is revealed that they do live together in another Pierce book, First Test. By the time of the Daughter of the Lioness duology, they are married and have children.
