Lore Olympus - Volume nine

"Persephone and Hades are finally reunited when the banished goddess of spring returns to the Underworld to claim her rightful place as queen. Now that Hades and Persephone have defeated and imprisoned the power-hungry Kronos once more, nothing can keep them apart, and years of being separated have only made their desire for each other grow. But the other Olympians can't help but meddle, pushing the pair to make things official with a coronation–and a wedding. Ignoring the others who try to define their relationship, Hades and Persephone choose to take things at their own pace and focus on rebuilding the Underworld. They begin by investigating how Kronos was first able to escape, and they learn the horrifying truth that he has captured a powerful young god whose abilities help Kronos project his thoughts outside of Tartarus–thoughts he uses to plague Hera's every waking moment. Though Kronos's physical form is locked away, Olympus will never be free until they can rescue the child from the furious Titan's grasp. To save the realms, Persephone must figure out her fertility goddess powers and embrace her role as Queen of the Underworld–even as it takes her further from her mother's expectations and her former place in the Mortal Realm."–
