In Blink & Caution (Candlewick, 2011) by Tim Wynne-Jones I never mistook whether I was hearing 17-year-old Caution or 16 year old Blink. Maybe that's why it won the Boston Globe-Horn Book Award for fiction for 2011!
These two runaway/street kids in Toronto are both in trouble. They meet through a con and despite herself, Caution wants to help Blink solve the mystery he witnessed. But can these two learn to trust each other?
This Tim Wynne-Jones is NOT the nuclear physicist, according to the author website. But there you can learn about the variety of books Tim has written, about all his awards, and more.
