Return to Siren Island

Lieutenant Kallach Mare had to rush away from Siren Island, leaving his father behind. However, his situation at home is less than grand, and his father needs a rescue. With Jack and Barry at his side, he returns to Siren Island to save the besotted sailors—his father included.
 

However, there's unrest on the island... and Jack and Kallach have returned to some rather disappointed bond mates.
