As female hormones decrease, they're replaced with an overwhelming urge to grow delphinium.

I believe without a single shadow of a doubt that it is necessary for young people to learn to make choices. Learning to make right choices is the only way they will survive in an increasingly frightening world.

I always set out to tell a good story, to create a character that young people can relate to, place them in a situation that will be interesting, intriguing, eventually suspenseful. But what I find is that after I do that, then there are themes that emerge, which teachers can then use to provoke discussion and debate.

When you lose a child in an accident as I did, it's final - you're not caught in this longing for him, to search for him, knowing he's out there some place.

I was lined up to do this honors degree course in biology, of all things, for no better reason than I got high marks in it.
