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... Return to the siren realm of A.L. 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. Pretty Little Mermaids will be a quadrilogy, not including Cobalt, but may include as many as 5 books.
