" Nikolai sat inside the shade of the vine shelter and watched a single nimbus of sunlight shine through the leaves and into Renata's dark hair while she slept. Ultraviolet light was toxic to his kind—lethal after about half an hour's sustained exposure—but he couldn't work up the desire to patch the small hole in the vegetation and snuff out the errant ray. Instead, for the past several minutes, he'd been sitting next to Renata and watching, admittedly, much too intrigued, as the light soaked into her ebony hair, infusing the silky strands with a dozen different shades of copper, bronze, and burgundy.
What the hell was wrong with him?
He was sitting there staring at her hair, for crissake. Not just staring, but staring with total rapt fascination. To Niko, that seemed to indicate one of two equally disturbing facts: Either he should seriously consider looking into night courses with Vidal Sassoon, or he was a complete goner when it came to this female.
Goner as in gone for good, ruined for any other. "
