I'm working on Song for the Undead right now, so here are 7 lines from page 77 of that:
“Those boils on his skin… they pop!” Kevin could see the sheen of yellow pus on his glove.
“Good thing we’re wearing gloves, eh?” he replied. “Looks like it’s stopping.”
The spasms had died down; the man’s body seemed to relax. Sam let go of him at once and backed away. Kevin released him more tentatively, but it seemed the fit had passed. The man’s jaw slackened. He was breathing raggedly. Then, all of a sudden, his head lurched back, his throat bubbled up, and he was vomiting, a small eruption of thin, orange-ish fluid that dribbled up his nose and down his chin.
Mmm, tasty! LOL Of course it was a vomiting scene; sometimes I feel like all I write are vomiting scenes.
