He shrugs. “Maybe she doesn’t know who we are.”

“What do you mean? Everyone knows who we are!”

“Obviously not. We’ve never met her before, remember?”

She snorts. “Are you dehydrated? She can see our mark. It’s not like we were hiding it.”

“Maybe she thinks it’s a tattoo,” he offers.

“A what?”

“Look around, Rayna. See the markings on that human girl’s ankle?” He points toward a man walking up the stairs. “See that male? He’s got markings—humans call them tattoos—all over him. Maybe she thought—”

Rayna holds up her hand. “Stop. She’d recognize the trident. If she was one of us.”

Galen nods. She’s right. A Syrena knows a Royal by the small blue trident on their stomach—and dressed for the human beach, it’s visible on both of them right now. So, she has blonde—white—hair, and didn’t recognize them as Royals. But he knows what he felt. And she does have the eyes.…

Rayna groans. “Oh, no.”

“What?”

“You’re making that face.”

“What face?”

“The face you make when you think you’re right.”

“Am I?” He watches Emma straddling the surfboard, splashing waves of saltwater in her friend’s face without mercy. He grins.

“We’re not going home, are we?” Rayna says, propping herself against the rail.

“Dr. Milligan doesn’t call for just anything. If he thinks it’s of interest, then it probably is. You can leave if you want, but I’m looking into it.” Dr. Milligan is one of the only humans Galen trusts. If the doctor were going to tell anyone about the Syrena’s existence, he would have done it the day Galen had saved his life all those years ago. Instead, Dr. Milligan returned the favor by denying he’d ever seen Galen—even when his scuba companions called the press. Since then, they had built a friendship by sharing sushi, afternoon swims, and most importantly, information. Dr. Milligan is a well-connected and highly respected oceanographer and the director of the Gulfarium here on the coast, in a prime position to monitor the activities of his professional colleagues.

When Galen received Dr. Milligan’s urgent voice mail yesterday about a blonde Syrena visiting the Gulfarium in human form, he swam the gulf in a day. If Dr. Milligan is right about Emma’s abilities, he’s found more than just a rule-breaking Syrena. The good doctor might have found the key to uniting two kingdoms.

But since Rayna’s specialty is not discretion—she would even tell on herself when she was younger—Galen knows he must keep this secret from her. Besides, he’s not sure he believes it himself. Even if he did believe it, if he could confirm it, would Emma do what she must? And where has she been? And why? Everything about Emma is a mystery. Her name doesn’t originate with the Syrena—or her hair or skin. And the way her lips turned red when she blushed almost knocked the breath out of him.

“What?” his sister asks.

“Nothing.” He wrenches his gaze from Emma. Now she’s got me muttering my thoughts out loud.

“I told you, you’re losing it.” Rayna makes a phlegmy gagging sound and wrings her hands around her neck. “This is what Father will do to me if I come home without you again. What should I say when he asks where you are? When he asks why you’re so obsessed with humans? ‘But Father, this one is a pretty blonde with nice contacts’?”

Galen scowls. “He’s going to regret not taking an interest in them. At least Grom’s reasonable about it. It’s only a matter of time before they discover us and—”

“I know, I know,” she drawls. “I know how you hate humans. Sheesh, I was just kidding. That’s why I follow you around, you know. In case you need help.”

Galen runs a hand through his hair and leans back over the railing. His twin sister does follow him around like a sucker fish, but being helpful has nothing to do with it. “Oh, are you sure it doesn’t have anything to do with settling down with—”

“Don’t even say it.”

“Well, what am I supposed to think? Ever since Toraf asked Father for you—”

“Toraf is foolish!”

Toraf has been their best friend since birth—that is, until he recently made his intentions toward Rayna clear. At least he had the good sense to hide out and wait for her death threats to subside. But now she gives him something worse than threats—complete indifference. No amount of pleading or coaxing from Toraf has thawed her. But since she turned twenty this spring—two years past the normal age of mating—Father couldn’t find a good reason not to agree to the match. Toraf is a good candidate, and the decision is made, whether Rayna chooses to ignore it or not.

“I’m starting to think you’re right. Who would want to attach himself to a wild animal?” Galen says, grinning.

“I’m not a wild animal! You’re the one who isolates yourself from everyone, choosing the company of humans over your own kind.”

“It’s my responsibility.”

“Because you asked for it!”

This is true. Galen, stealing an old human saying about keeping your friends close and your enemies closer, asked his older brother, Grom, for permission to serve as an ambassador of sorts to the humans. Grom, being the next in line for kingship, agreed with the need to be cautious about the land dwellers. He granted Galen exclusive immunity to the law prohibiting interaction with humans, recognizing that some communication would be necessary and for the greater good. “Because no one else would. Someone has to watch them. Are we really having this conversation again?” Galen says.
