“Come on, Eva. Think,” Callum told her. He’d come back from his ride and had changed shirts into something lighter. The Greek sun seemed hotter to him in the afternoon. They had the library to themselves—a large, airy room lined with bookcases and books in Greek, English and Latin. Someone here knew their stuff, but that wasn’t Eva.

Eva pulled a face—just like a kid. “I know the answer.”

“So why don’t you tell me?” He leaned back in his chair. The leather squeaked. The rugs in here were all Persian silk and the chairs tall, big and comfortable. Callum took another sip of the Greek coffee Gaia had brought them along with fruit and slices of a spiced raisin cake Eva had told him was fanouropita. The pita part he recognized—Greek food in New York was some of the best in the city, but Athens kept surprising him with things he’d never heard of. He wished Eva would surprise him.

It seemed to him that she’d done everything she could this afternoon to get some sort of reaction from him. She’d come in wearing a tight, short dress. She had her hair down and kept fiddling with it, more like she was in a bar instead of a make-shift classroom.

“Eva?” He made the word a caution—he really was losing his patience with her.

She gave a shrug and a smile. “Sorry. I was just thinking here we are—both young, both unattached, and what do we do? Do we go out? No, we sit in a room and look at books.”

Callum stiffened. “What’s wrong with books?”

“Nothing. But don’t you want to see the sights of Greece? Don’t you want to go to some clubs? Don’t you want to live a little.”

“That is not my job.” He frowned at her and started to tap on the chair arm. Something she’d said had given him an idea—maybe a way to reach her. “You do know Greece is the birth place of modern science. The great philosophers taught us ways to look at the world—to analyze, to think. They didn’t always get it right, but they gave us a foundation that still holds up all our modern science.”

She twirled a lock of hair around a finger. “And you think I shouldn’t disappoint them? I want to be an artist, not a scientist.”

He blinked at her—he’d just been wondering if her hair was soft or wiry. Sitting up, he cleared his throat. “There’s science in art. It takes chemistry to mix colors. Geometry to adjust scale and determine proportions. Science and art have always been close sisters.”

Eva closed her book with a thump. “I wish my sister was here. I could beg Alexandra to rescue me.”

A soft knock sounded on the open door and Gaia stepped in to the room. She smoothed her black dress with her hands. “Excuse me, Miss Eva. My daughter just called and she is getting ready to have her baby. Her husband is still at sea and she needs me to come to Patras right away. I would ask your brother but he said he and Claire are spending a few days in Athens and may need to fly to London.”

Eva stood and walked over to take Gaia’s hands.“Of course you must go. Antonio’s pilot can fly you there so you don’t have to drive.”

“But I—“

“Gaia, you are almost family. Go. Tell your daughter we are all thinking of her, and let us know what they name the baby.”

“If you are sure…ephkharisto, Eva.”

Callum watched the older woman hurry away. He tipped his head to the side. He’d never seen this side of Eva. He’d thought she was too self-involved to even think about others, but it was obvious she cared for Gaia. She watched after Gaia, and then turned to Callum. “Guess we’re going to be on our own for the next several days.”

Callum saw a spark in those dark, dark eyes. He was having trouble keeping his eyes off the deep vee of her dress and how the tight fabric clung to the swell of her breasts. His pulse quickened. We need to get out of here and surround ourselves with other people. Standing, he grabbed her wrist. “Come on. I’ve got an idea about how to teach you a little science by going to the source.”

Eva looked at him with wide eyes, but she followed as he led her to the garage. “Really?” She frowned. “Wait—we’re taking the books with us?”

“Not books. I need to show you how geometry was used to build the perfection of the Parthenon—those columns aren’t just works of art, they used science to determine the perfect height and width. And then we’re going to check out some other spots.”

“A club?” Eva asked.

He heard the hope in her voice. Turning to her, he looked her up and down. She really was just a kid in some ways—a kid who’d never had to think or work hard. He made up his mind. “Make you a deal—you come with me to the Acropolis and if you can show me you actually know something about the Parthenon, and if you learn three new things, then we’ll stop for dinner. And a club.”

She clapped her hands and gave a small jump. “Really—you mean it? We’ll have some fun?”

He frowned at her. It seemed to him she was acting more pleased that she really was—he didn’t see the enthusiasm in her eyes for his idea. She linked her arm through his and started pulling him with her. “I’ve never ridden on a motorbike before. I’ll have to wrap my arms around your waist to hold on, and press up tight against you.”

Callum swallowed the lump in his throat. Maybe this hadn’t been such a great idea, but he was stuck—with her hanging onto him. He glanced at her. “Maybe you should change first. Jeans. Boots if you have them. If I spill I’m not leaving your skin on the streets of Athens.”

She waved a hand. “You won’t spill. I’m sure you won’t.”

“Yeah, well, I’m not taking chances. I’ll go grab the bike and meet you out front. Don’t be long.” Callum turned and headed out to the garage. At least he’d get her out of that short, short dress and he wouldn’t have her bare legs wrapped around him. He put his thoughts on the lessons they could go over at the Parthenon—he hadn’t been lying when he’d said there was good science behind the ruins, and not just aesthetic reasons for its construction.

But he kept thinking about how Eva’s eyes had lit up when Gaia had mentioned her daughter was having a baby. There was more to Eva than just a dumb rich girl who thought only of clothes and more clothes. And suddenly he wanted to find out why she was hiding that part of her from everyone.
