But then Eureka thought about Ander, who insisted Brooks was dangerous. The scar on Brooks’s forehead was half hidden under the shadow of his baseball cap. It looked like an ordinary scar, not some ancient hieroglyph—and for a moment Eureka felt crazy for thinking that the scar might be evidence of something sinister. She looked down at the thunderstone, flipping it over. The rings were barely visible in the sun. She’d been acting like a conspiracy theorist who’d spent too many days cooped up with only the Internet to talk to. She needed to relax and get some sun.
“Thanks for lunch,” Eureka said to Aileen, who’d been chatting with the twins from the gangplank. She stepped closer and lowered her voice so that Aileen alone could hear. “About Brooks.” She shrugged, attempting lightness. “Just boys, you know. I’m sure William will grow up to terrorize Rhoda someday.” She tousled her brother’s hair. “Means he loves you.”
Aileen looked out at the water again. “Children grow up so fast. I guess sometimes they forget to forgive us. Well”—she looked back at Eureka, forced a smile—“you kids have fun. And if there’s any weather, turn back right away.”
Brooks held out his arms and looked up at the sky, which was blue and immense and cloudless but for an innocent cotton puff in the east just underneath the sun. “What could possibly go wrong?”
The breeze rustling Eureka’s ponytail became bracing as Brooks started Ariel’s engine and steered away from the dock. The twins squealed, looking cute in their life jackets. They balled their hands into excited fists at the first jolt of the boat. The tide was soft and steady, the air perfectly briny. The shore was lined with cypress trees and family camps.
When Eureka rose from her bench to see if Brooks needed help, he waved for her to sit down. “Everything’s under control. You just relax.”
Though anyone else would say that Brooks was trying to make amends and that the bay today was serene—a sun-blasted sky making the waves glisten, the smallest shimmer of pale fog lazing on the distant horizon—Eureka was uneasy. She saw the sea and Brooks as capable of the same dark surprise: out of nowhere they could morph into knives and stab you in the heart.
She thought she’d hit the bottom at the Trejean party the other night, but since then Eureka had lost both The Book of Love and the only person who could help her understand it. Worse, she believed that the people who killed Madame Blavatsky were the same ones hunting her. She really could have used a friend—and yet she found it nearly impossible to smile at Brooks across the deck.
The deck was made of treated cedar, dimpled by a million dents from cocktail-partiers’ stilettos. Diana used to go to Aileen’s parties on this boat. Any of these marks could have been made by the single pair of high heels she’d owned. Eureka imagined using her mother’s dents to clone her back to life, to put her on the deck right now, dancing to no music in daylight. She imagined that the surface of her own heart probably looked like this deck. Love was a dance floor, where everyone you lost left a mark behind.
Bare feet slapped the deck as the twins ran around, shouting “Goodbye!” or “We’re sailing!” to every camp they passed. The sun warmed Eureka’s shoulders and reminded her to show her siblings a beautiful time. She wished Dad were here to see their faces. With her phone, she snapped a picture and texted it to him. Brooks grinned at her. She nodded back.
They glided past two men in mesh baseball caps fishing from an aluminum canoe. Brooks greeted each of them by name. They watched a crabbing boat coast by. The water was rich blue opal. It smelled like Eureka’s childhood, much of which had been spent on this boat with Brooks’s uncle Jack at the helm. Now Brooks was steering the ship with easy confidence. His brother, Seth, always said that Brooks was born to sail, that he wouldn’t be surprised if Brooks became an admiral in the navy or a tour guide in the Galápagos. Whatever kept Brooks on the water was likely what Brooks would do.
