Isolated . . . Verdant String scientist, Anja Farucci, is frightened. Her calls for help from her remote coastal research station on the moon Fynian have been going unanswered, and strange things are happening with the leviathan pod she's studying. Out of options, she sets out on the dangerous three-day journey to Rinc, Fynian's only city. Stranded . . . Cal is a wave rider, and if anyone understands leviathans, it's him, but when Kada, a young leviathan, grabs his boat and strands him on the southern peninsula, Cal is at a loss to understand what is going on. Thrown together . . . When Cal and Anja cross paths, they discover Anja's communications have been deliberately sabotaged. Someone doesn't want anyone coming or going from the southern peninsula. When the people involved start hurting leviathans, though, neither Cal nor Anja can let it go. What they don't know, as they get deeper and deeper into the mystery, is that the secret they discover in the cold waters of Fynian's ocean will change them forever. Wave Rider is the fifth book in the Verdant String series but like the others can be read as a standalone novel.
