Nonchalant. Suave. But really, are there any nonchalant, suave good-byes that involve unruly crustaceans? Not to mention that the Good Ship Pretense of Nonchalance sailed several blatherings ago.

“Will I?” Cass calls after me. I pick up my pace but can’t resist a quick reverse look at him. He just stands there, arms still folded, watching me scurry off like some hard-shelled creature scrabbling over the seafloor. Except without the handy armor.

I keep speed-walking down Low Road, my thoughts racing ahead of my feet. The yard boy is everywhere on island, all summer long. Cass will haunt my summer the way he preoccupied my spring.

I hear a sound behind me, rubber on sand, skidding. I turn, my breath catching. But it’s just Vivien, bouncing over the speed bump on her old-fashioned, sky-blue Schwinn with the wicker basket, legs kicked out. She looks, deceptively, like an ad for something wholesome. Butter. Milk. Fresh fruit. Her glossy brown hair is caught up in pigtails that don’t look stupid, her cheeks glowing in the heat.

“Hey!” she says. “Your mom told me where you were going. Wanted to say good luck.”

“I thought you were meeting up with Nic.”

Vivien flushes the way she always does at Nic’s name, the thought of Nic, the sight of him. Yes, things have shifted, rearranging our childhood trio into something different.

She shakes her head. “I talked him into applying for the island painting and repair gig. He’s interviewing with Marco and Tony right now. If that works out, please God, he won’t have to rely on Hoop’s connections to get sketchy painting jobs all over the state.” She rolls her eyes. “That was a good idea . . . why?”

“Hoop’s an idiot,” I say. Nic’s best friend and partner for the summer in the house-painting business, Nat Hooper, can make a disaster of anything, and Nic is far too good-natured to stop him.

I hear the zzzzzzz of the mower starting up again. It takes all my concentration not to look back over my shoulder. Did Vivien see Cass? She must’ve.

“Hey, want to work a clambake with me Friday night?” Vivie asks. “Mom and Al are catering a rehearsal dinner. Ver-ry fahn-cy. It’s on the Hill—okay with that?”

“Absolutely. Nic up for it too?”

“Oh, for sure. We’ve got the bar covered, but low on waiters and servers. Hoop’s not sure he can make it—might have ‘a hot date with a special lady.’ Although I’m thinking the special lady is digitized. D’you know any other guy who’d be willing?”

I can’t help shifting my eyes down the road. Vivien trails my gaze, and then stares back at me with a little crinkle between her eyebrows.

“Have you seen this year’s yard boy?” I ask, wary.

“Yup.” She watches my face. “I gave him the gate code when he drove in to report for duty this morning.”

“You didn’t think to mention it to me? No warning text? Nothing?”

“Oh shit, sorry.” Viv lowers her heels to regain bike balance. “I tried once, but you know how cell reception sucks here.” She sneaks another look over her shoulder. “I should have kept trying.”

I follow her eyes back to the Partridge house, where Cass has dutifully returned to mowing the lawn. Horizontally. Shirt off again, hair gleaming in the sun.

My God.

“What, Gwenners? Thinking of asking Cassidy to be a spare set of hands?” She tips her head at me, eyes twinkling.

“No! What? No! You know my policy. Hands off. Avoid at all cost.”

Vivien snorts. “You sure? Because you’re getting that glazed look that leads to bad judgment, impulsive decision-making, and a walk of shame.”

Even though it’s Vivie, no real criticism there, I can feel my face go red. I look down at the ground, kick aside a pebble. “There were only two actual walks of shame.”

Vivien’s face sobers. She flings her leg over the bike and knocks back the kickstand, moves closer. “Cassidy Somers . . . right here on the island. Just . . . watch your step, Gwenners. Be careful with yourself.” Her fierce expression is so at odds with her sweet face and my childhood nickname that I want to laugh, but there’s a little twist in my stomach too.

We all can’t be Vivie and Nic.

My cousin and my best friend have been an item since we were all five, when I ceremonially performed their wedding service on Sandy Claw Beach. Since we were more familiar with boat launchings than weddings, I bashed them both on the knees with a bottle of apple juice.

How many people, honestly, get the guy they’ve loved all their lives treating them like they’re rare and precious and deserving of adoration? Hardly anyone, right?

Still, there’s a big gap between that and some unseemly scuffling in the sand.

Or a bunk bed.

Or a Bronco.

“Gwen!” Vivie snaps her fingers. “Stay with me, here. Remember your promise. Want your dad to catch you rolling around on the beach again, like with”—she hesitates, lowers her voice—“Alex?”

I cringe, turn my back on the Partridges’ lawn. Then I hold up one hand, resting the other on an imaginary Bible. “I remember. From now on, I will not, no matter how tempted, get even close to a compromising position with someone unless I love them and they love me.”

“And?”

“And unless we’ve passed a lie detector test to prove this,” I finish obediently. “But I have to say, that’s going to be awkward. Carrying around all the equipment, setting it up . . .”

“Just stay out of the sand dunes. And far away from those parties on the Hill,” Vivien says. “When it’s real love, no equipment necessary. You just look in their eyes and it’s all there.”

“Go apply for that job at Hallmark right this instant!” I swat her on the shoulder. She ducks away, kicking the bike back into gear, laughing.

I wouldn’t pass the lie detector test myself if I didn’t say that, oh, I want what Vivien and Nic found without even having to search. I give one last look over my shoulder at the back of Cass’ uptilted head, as Mrs. Partridge once again bellows at him from the porch.

The Ellington house is the last one on the beach—big, turn-of-the-last-century, graceful, stretching along the shore like a contented cat in the sun. It’s got weathered dove-gray shingles and gray-green trim, two turrets, and a porch that sweeps three-quarters around, like the tail of a cat cozying close.

Taken with all that, the carport where Mrs. E.’s Cadillac is parked looks so . . . wrong. There should be a carriage house there, an eager groom in livery waiting to take the reins of your horse.

I walk up the side path to the kitchen door, wondering if this is the correct thing to do. You never know on the island. Half the houses Mom cleans welcome her in the front and offer her a drink, the other half insist she go around back and take off her shoes.

Toeing off my flip-flops, I look down at my feet, wishing for a second I had dainty ones like Viv, or that my nails were decorated with polish and not a Band-Aid from stubbing my toe on the seawall.

Mrs. Ellington’s glossy oak side door is propped open by a worn brick, but the screen door is closed. “Hi . . . ?” I call down the shady hallway. “Um, hello? . . . Mrs. Ellington?”

A television murmurs in the distance. A porcelain clock shaped like a starfish ticks loudly. From where I am I can see the gleam of a silver pitcher on the kitchen table, a tumble of zinnias glowing in it. I put my hand on the screen door, poised to push it open, then hesitate and call out again.

This time, the TV is immediately silenced. Then I hear click/thump, click/thump coming down the hardwood floor of the hallway, and there’s Mrs. Ellington. Her hair’s whiter and she’s holding a cane, one ankle tightly wrapped in an Ace bandage, but she’s still beautifully dressed, pearls on, smile broad.
