“I’ll stay,” Will said a bit crossly, and threw himself down in the armchair Tessa had just vacated. “I can minister angelically.”
“None too convincingly. And you’re not as pretty to look at as Tessa is,” Jem said, closing his eyes as he leaned back against the pillow.
“How rude. Many who have gazed upon me have compared it to gazing at the radiance of the sun.”
Jem still had his eyes closed. “If they mean that it gives you a headache, they aren’t wrong.”
