Sarah heads the North American side of the Greenhouse (she's originally from London, and Greenhouse operates in the U.S., Canada, and in the UK). She has more than 25 years’ experience of children’s publishing. She's worked at Collins (before it was HarperCollins), Transworld/Random House, and at Macmillan Children’s Books in London. Sarah is an experienced speaker on issues connected with children’s books and creative writing and attends international bookfairs, American writers’ conferences, and industry events throughout the year.

Here's a little bit of what Sarah's looking for in authors (from an interview on Literary Rambles).
I like authors who can make me laugh or cry, who can make me see the world in some new way--who make me want to leap to the phone to call them as soon as I've turned the last page. I also love authors who can do great action (very rare) and big stories that engage the intellect as well as the heart (also rare). Oh, and sharp, snappy commercial writing with a strong hook. But I also have a passion for beautiful, powerful language and therefore adore writers who can weave magic with their words (which means, yes, I will take on a literary novel if I have a strong enough belief in the author).
