"Maelstrom"
*The long-docile race of the Blue no longer want solitude in their underwater habitat after the human's latest attack -- they now want revenge! After thwarting the invasion of the Blue cities by Admiral Maylander's Navy, Aspen Matthews and Chance Calloway have found some much needed seclusion together in a beach house south of the border. But, their romantic getaway will be short-lived as the return of the murderous Killian, now at full-strength, is ready to strike once more against the humans -- along with his reunited daughter, Kiani! Plus, the hatred from below the surface is also shared by one other race -- the ancient and most powerful underwater beings known as the Black! However, the U.S. Navy has plans of their own for the Blue, as well as a new leader with special ties to both Aspen and Chance! *Source: aspenstore.com
