The danger, the secrets, and the lies leave Olivia wondering if there’s anyone above the waves or below she can trust. It’s been over a year since San Diego. Now in college at the University of Maryland, Olivia has new friends and a promising marine biology internship. But moving on from her past proves a lot harder than she expected. Burdened by loneliness, Olivia can’t shake the feeling that there’s something else for her. Something more. Then, during one of her regular visits to the Baltimore Aquarium, a mysterious woman approaches Olivia, begging for help. A woman with gills and purple fingernails. Seeing the woman's desperation, Olivia agrees without question—sure that a simple rescue will show Eamon O’Dell she’s ready to join him and the others on their tasks to aid merpeople. But what should have been a good deed has set off a series of deadly attacks that put Olivia in mortal danger, changing everything she thought she knew about the merworld. Trusted friends have become little more than strangers. New enemies arise with lethal prejudices. Tensions between the worlds are at an all-time high and someone is pulling the strings to further damage the tenuous peace that Eamon and his friends have worked hard to build. If Olivia can’t find out who’s behind it all, and convince the merworld council known as CHASM to maintain alliances with humans, her life, and the lives of everyone she loves, are forfeit. The adventure continues in CHASM, book two in the Fathom series.
