True love can withstand distance and time...but can it survive immortality? Over her more than a century as a mermaid, Alexis Silver never really questioned how her first husband had such an effect on her despite the brief time they had together. She tried a few relationships with other immortals, though none lasted. She's content to be on her own, chasing the kind of adventures her mortal life would never have offered. Licinia, suspecting Alex isn’t over Albert, suggests they take a trip to the land once called Ptolemais. Curious to see what magical surprises her dark master friend has up her ethereal sleeves, Alex agrees. But not long after arriving in Cairo, they hit a snag. Licinia wants to conduct a ritual. But the only source of rare, magical components won't part with them unless the fate of his missing daughter is discovered. Alex soon realizes the woman's disappearance is far from ordinary. In fact, it's downright demonic.
