O WHAT DO you do if you have thirteen hours to kill before you rescue your mom? Well, if you’re wacky, devil-may-care bird kids, you go swimming!

Pearl Harbor was in a bay off the coast of Oahu,this close to Honolulu. In fact,Honolulu means “sheltered bay,” according to a little sign by the mess hall. (See? Who says you never learn nothin’, hanging out with us?)

Some of the shoreline near the base was off-limits, but there was a public part too. Despite it being early evening, the weather was perfect and balmy, and the water was blissfully warm. The beach wasn’t crowded, but there were people swimming and collecting shells. I was starting to see Fang’s point about just finding a tropical isle and letting the rest of the world go crazy without us.

“Keep your Windbreaker on,” I told Angel, who was shimmying out of her tiny uniform. “Bird kids weren’t exactly designed for bathing suits.”

She made a face but nodded. “I think there’s like dolphins or something out there. I can hear things thinking, but they’re not human.”

Concern shot through me. “Not human? Do they feel evil? They’re not, like, Erasers with fins or something, right?”

Angel giggled. “No. They’re not Erasers. And they feel totally not evil. Okay, bye!” She ran across the sand and threw herself into the water. I watched as her golden curls submerged and disappeared. I sighed and sank down on the sand next to Akila and Total.

Fang sat next to me, still looking out of character in nonblack clothes.

“Whoa. Khaki much?” I couldn’t resist saying.

He looked at me. “Uh-huh. And I dig your military hair.”

“Touché.” Self-consciously, I touched the tight French braid I was required to wear here at the navy fun house.

Gazzy and Iggy were already in swimming trunks, racing toward the ocean. They yelled when they hit the waves, plunging in far enough to bodysurf.

Fang’s dark eyes scanned the water. He was counting heads, the way I was. I hadn’t gotten over the feeling that something was wrong because Nudge wasn’t here.

“How long’s she been under?” Fang asked.

“About five minutes. She said there were dolphins. Or something.”

We sat together silently for a while. Gazzy and Iggy were shouting and splashing in the water. Angel still hadn’t come up for air, and I tried to let go of the normal expectation that she needed to. After all, what are a few gills among friends?

Suddenly Angel did pop up, smiling and waving, heading toward us. “It’s totally awesome, clear and blue,” she announced, shaking off water.

“Were there dolphins?” I asked.

She nodded. “Yeah. They’re really mad. Hey, Total. Come out with me. Practice breathing under water.”

Total wrinkled his nose. “No gills,” he said. “And I’m still getting used to the wings.”

I was stuck on the angry dolphins, but Angel frowned at Total, then at me and Fang. “You guys all really need to practice breathing under water,” she said urgently. “It’s really important. I want you to practice right now.”

“Sweetie, I don’t think any of us can breathe under water except you,” I said. “Remember when Gazzy tried? He barfed up half the ocean. And what do you mean, the dolphins are mad?”

“I really think you guys should try,” Angel said, wearing her familiar and dreaded “I’m not gonna let this go” expression. “You might have developed gills by now.”

“Don’t think so,” I said. “Now, back to the angry dolphins—“

A piercing scream stopped me, and Fang and I leaped to our feet.

A woman was standing at the edge of the ocean, pointing frantically at a small boy being swept out to sea. “A riptide got him!” the woman screamed. “Someone help him! Call nine-one-one!” She plunged into the water but stopped when it reached her waist.

Gazzy and Iggy had set off after the kid, but the tide had pulled him amazingly far out in just a few moments. Fang and I looked at each other, then whipped off our jackets at the same time. Ignoring all the bystanders, we sped across the sand. Right as we reached the small cresting waves of the ocean, we snapped out our wings and jumped up into the air.

Working powerfully, we raced low over the water. The spray misted my face, the wind whipped through my hair, and I could smell the salt air. We were flying again. It felt like we hardly ever got a chance to anymore.

We were incredibly fast, but not fast enough. When we were almost there, the boy sank beneath the waves, his small arms still reaching up. In an instant, we angled down sharply, folding back our wings, and hit the water.

It was so clear that we immediately saw the kid’s bright red rash-guard shirt. His eyes were closed, his face still and pale in the aqua light. We each grabbed an arm, then shot up toward the surface with as much force as we could, popping out of the water like corks, hoping we could get airborne.

It worked. Our wings brushed against each other, but we managed to get aloft and streaked back to land. Sadly, our landing was less than graceful because of our shared cargo, but we thunked to a stop in the sand without falling and put the boy down.

“I know CPR!” a man shouted, already kneeling. Within less than a minute, the little boy was gagging and retching, then gasping for air. “Mom?” he choked out, and then the woman hauled him into her arms. They were both crying, holding each other tight.

Fang and I faded back to where the flock was waiting with Total and Akila.

Angel looked at us accusingly. “You didn’t even practice breathing under water just now, did you?”
