Loose lips arent the only thing that can sink shipsbut sending submarines into Sirenas seas can only lead to one thing warWilliam said that Singapore would fall but Sirena didnt expect it to happen while she was thereWith a submarine on her tail as she tries to preserve her grandfathers precious treasure Sirena finds herself on the other side of the ocean from her daughtersand with no choice but to fight to protect the human city she once called homeWith the human world at war on land air and sea one siren will answer the call But it will take more than one siren to win this war
