Our enchanted Deliverers, Rheyden and Rhiannon, find themselves at the mercy of the goddess Aquina's treacherous seas while in hot pursuit of the villainous Yurgon. If the General is successful, the Craetes music box will raise the dreaded Nagas from the sea depths, leaving the water kingdoms at his vicious mercy. There's only one problem: no one seems to know how to get there, and the twins are doubting themselves now more than ever. After a series of treacherous mishaps, the twins are forced to ask themselves hard questions about their identity--and their willingness to be the saviors the Four Realms need. Rhiannon struggles to come to terms with Audax's betrayal, and Rheyden strives to heal from the death toll rising around them. To the spirit world and back again, can The Two resurrect from their individual hurts and save the water kingdoms before the Nagas strikes again?
