Summary

With less than two hours before the reply deadline, Ana and her crew face a daunting task: they must craft a response in the same blue whale/five by five/Bundeli code they just decrypted, without access to the internet or any translation machine. The pressure is immense, and Ana acknowledges that they must rely on their training and best guesses.

Ana immediately thinks of Virgil's offline whale-song simulator app, which he downloaded in full. She sends Gem with Virgil to retrieve the phone from the lockbox, reminding them to keep it offline. Meanwhile, Jack fetches Nelinha, and the two begin adapting the LOCUS to transmit messages rather than just receive them. Lee-Ann works on a new encryption base, understanding that they can't simply repeat the same algorithm—they need to change the register, like modulating to a new key in a song. Halimah and Ana brainstorm Bundeli phrases, starting with a request not to fire.

After ninety minutes of intense work, the crew finishes encoding their transmission. The message identifies their ship as Varuna from HP, requests no fire, describes an emergency situation, and notes that Ana Dakkar is aboard. Ana feels self-conscious about using her name, but the other Dolphins convinced her it's necessary—if she's valuable enough, her presence might deter an attack.

Before transmitting, Ana gathers the crew on the main deck. She explains the risks: sending the signal reveals their position, and if the message is incorrect, they could be under attack within minutes. Gem corrects her estimate from fifteen minutes to eleven. Despite the tension, some classmates crack smiles at the nervous humor. Ana orders general quarters, and Nelinha transmits the message.

The crew waits. An hour passes with no response. At sunset, Ana orders the engines stopped and transmits again. Still nothing. Ana begins to doubt herself, cursing her belief in Dr. Hewett's map and wondering how long they can survive with no food or water.

Then, directly off the bow, the air ripples as if a mile-wide curtain of mirrors shatters. A camouflaged island appears—a volcanic peak rising three hundred feet, surrounded by a turquoise lagoon and a ring of white beaches. A break in the atoll forms a natural gateway.

A woman's voice crackles over the intercom, identifying the island as Lincoln Base. She warns that any sign of aggressive intent will result in destruction, and that they will also be destroyed if Ana Dakkar isn't aboard, safe and unharmed. Then, in a surprising shift, she asks how many will be joining them for dinner—Jupiter is baking lasagna.
