Isabel herself could hardly have put into words the new feeling – excitement, perhaps – she felt every time she saw this man. There was something mysterious about him – as though, behind his smile, he was still far away. She wanted to get to the heart of him.

Life could snatch away the things you treasured, and there was no getting them back. She began to feel an urgency, a need to seize an opportunity. Before anyone else did.
