A keen young freshman. A siren at a crossroads. A chance meeting that changes everything.

Gina is a mermaid—a siren—on her land cycle and she has found a human mate she loves. In fact, they're engaged, but to overcome a mysterious betrayal she isn't sure she should forgive, she needs some time at sea, ideally above it.
So she stows away on a tall ship.
Seth is a precocious fifteen-year-old working on a school project, researching Cobalt Girl, a modern sailing vessel.
A chance meeting and a fog bank along the Carolina coast will change both of their lives forever…

Knorr with Cobalt, a novella-length prequel to a forthcoming series entitled Pretty Little Mermaids, which expands the lore and worlds established in Born of Water, Mermaid’s Return and The Siren’s Curse, but is set before the events of the latter. Only available in ebook and audio; included in paperback edition of Aquamarine.
