True love can withstand distance and time... but can it survive immortality?

Over more than a century as a mermaid, Alexis Silver never really questioned the profound effect her first husband had on her, despite their brief time together. She’s tried a few relationships with other immortals, but none lasted. Content to be on her own, Alex chases the kind of adventures her mortal life could never offer.

When her dark master friend Licinia suggests a trip to the land once called Ptolemais, Alex's curiosity is piqued. However, when their jaunt hits a snag. Licinia wants to conduct a ritual to fix it, but the only source of the rare magical components she needs demands a favor: they must find his missing daughter.

As Alex delves into the case, she soon realizes the girl's disappearance is far from ordinary. In fact, it’s downright demonic.

Silver Heart is the fifth book in the Alexis Silver series of underwater-themed mysteries and adventures, and is part of the broader Vampire for Hire world.
