The Greek's Reluctant Guest. Moonstone Romances, #1

Sent to the glittering Greek island of Thalassos under circumstances she barely understands, Charlotte Mitchell expects an awkward business errand, not a confrontation with the island's most dangerous man. Nikos Stavros is wealthy, powerful, and impossible to ignore, a shipping magnate whose presence fills every room and whose suspicions cut as sharply as his pride. From the moment Charlotte arrives, Nikos believes the worst of her.
To him, she is tied too closely to Richard Pemberton, the man whose schemes have left damage in their wake. To Charlotte, Nikos is arrogant, ruthless, and far too accustomed to obedience. Yet when circumstances leave her stranded beneath his roof, she has no choice but to become his reluctant guest. Kalista should be paradise: whitewashed terraces, dark blue seas, jasmine-scented nights, and sunlight spilling over marble courtyards.
But inside Nikos's house, every glance feels like a challenge, every conversation threatens to expose old wounds, and every moment of enforced closeness draws Charlotte deeper into a dangerous attraction she cannot afford. Nikos tells himself Charlotte is not to be trusted. Charlotte tells herself she despises him. But pride is a fragile defense against desire, and the longer they circle each other, the harder it becomes to tell the difference between resentment and longing.
When the truth behind Charlotte's arrival begins to unravel, both must decide whether the passion growing between them is only another deception, or the one thing neither of them can escape.
