Caught — Emma Shelford

Marine biologist Corrie Duval has so many questions about the strange fish she found. Unfortunately, her results aren't giving her clear answers, and her professor is growing suspicious about her late-night analyses and secretive manner.

Zeballos Artino still searches for his own answers, but he's not the only one. Someone is following his boat, and if Zeb won't tell them what he knows about the strange fish and its bizarre effects, they will make him talk.

Corrie and Zeb fall deeper into a world of cut-throat henchmen and scheming tycoons who are on the hunt for the same thing they are -- mysterious creatures in the sea.

This is book 2 of the Nautilus Legends.
