“Fitz pulled her forward, and the warm tingling in her hand shot through her body--like a million feathers swelling underneath her skin, tickling her from the inside out.”

“His power reached out to her like physical touch of a lover, sending tingles over her skin. His sculptured body moved in a sensual, yet deadly manner. Her hands itched to touch him, to feel his warm skin under her palms. She closed her eyes to stop the urge to go to him, shivered, and cursed her body for responding to him.”

“She looked up from closing it to find Jace watching her through hooded eyes. “And one last thing,” he said. He reached over and pulled the sparking pins out of her hair, so that it fell in warm heavy curls down her neck. The sensation of hair tickling her bare skin was unfamiliar and oddly pleasant. “Much better,” he said, and she thought this time that maybe his voice was uneven too.”

“She (Annabeth) put her hand on my spine, and my skin tingled. I (Percy) moved her fingers to the one spot that grounded me to my mortal life. A thousand volts of electricity seemed to arc through my body.”

“4 million volts course like lovers through her body. Eerie rays eliminate from bulbous cathodes to caress her skin penetrating deep. Also somewhat like lovers, actually. Chemicals so secret they don't even have names and bubbles and spurts in her vein.”

“Like electricity running through her body or the thick velvet of magic making everything tingle; she was hot and cold and shivering from both, her sense in total overload. - City of Ghosts”
