Sarah Davies (Agent representing US/Canadian authors)

Sarah founded the Greenhouse when she moved to the US in 2007 after a long career as a UK children’s publisher. She now divides her time between London and New York.

Sarah has been an editor most of her life and has considerable experience in contract negotiation, marketing and rights. Excellent publishing contacts in both the USA and Britain, and many years spent living in both countries, have given her an unusually transatlantic view of the children’s books industry, from both sides of the desk.  A member of AAR, Sarah has crossed America and Europe talking about children’s books and writing craft. She says, ‘Everything you need to know about Greenhouse is in its name.’

What Sarah is seeking:
Fiction by North American authors, from Middle Grade through Young Adult and across all genres (note: she is currently closed to debut Picturebooks but does rep PBs by clients whom she’s initially taken on for older fiction). She loves strong, hooky, layered plots, writing that is gorgeous but also conceptually strong, stories that are really moving but make you think too.


In YA, she is currently keen to find big, magical worlds derived from non-Western mythologies; unique and hooky contemporary fiction – perhaps involving unreliable narrators and/or interesting perspectives, structures or timelines; multicultural settings and diverse #ownvoices characters (and authors); magical realism – perhaps where the “real” is skewed by some other dimension. She loves stories involving the ocean, intriguing mysteries, relateable history (whether French Revolution or World Wars), and richly portrayed characters and settings of all kinds.

In MG, she is looking for pacy/adventurous fiction, but also classic-voiced and heartfelt stories for girls. She loves stories of friendships, magical realism (again!), and new ways of interpreting the classic “coming of age” trope. Again, she looks for a fresh hook, matched by strong writing.

Sarah will be attending:  London International Book Fair: April 10-12.

Polly Nolan (Agent representing UK, Irish & Commonwealth authors)

Polly joined Greenhouse in June 2013 as our UK agent. This was after a long and distinguished career at many of the UK’s top children’s publishing houses, where she worked in roles that bridged the spectrum from Junior Editor to Publishing Director. Polly made the move into agenting to do more of what she enjoys most – finding new writing talent, helping to develop great fiction, and achieving publishing deals for authors both new and established.  She has an enviable record as a talent-spotter and experienced nurturer of writers.  She has immense experience of contract negotiation and a keen understanding of the subtleties and nuances – beyond advance level – that make a really good publication offer.


What Polly is seeking: UK, Irish, Commonwealth (including Australia, NZ) and European authors writing in English for children and Young Adults. Outstanding writing. She is open to most genres and is always looking for those rare and wonderful novels in which she can lose herself completely. You know: the types where you start by thinking, I’ll just read this for 10 minutes and suddenly hours have disappeared.

Original, compelling story is key, as is uniqueness of voice. She is after novels that pull at the heartstrings, make her care deeply about characters that feel real but that also make her think. She believes that exceptional novels confound genres and so finds it easier to list what she isn’t searching for than what she is.  So:  please do not send Polly ‘cross over’ novels or books where the protagonist is a talking bird (though she does love a good animal story).  She wouldn’t jump on sci-fi (particularly ones with aliens, for middle grade readers) and she avoids stories that feel didactic or earnest in their message.  At the moment, she isn’t looking for dystopian YA.  Polly represents a very small number of picture book authors but only where they also illustrate their work.  However, if you have an exceptional story to tell and can do so in a distinctive way, she can’t wait to hear from you.  Finally, Polly would be grateful if you could follow our submission guidelines (have a look under ‘Submissions’ on this site). This allows her to manage the many queries she receives and get back to you efficiently.

Polly will be attending:  SCBWI British Isles Conference, taking part in ‘The Hook’ on Saturday 25th November, at the University of Winchester.  She is also part of the judging panel for the SCBWI ‘Undiscovered Voices’ anthology 2018.

On February 3rd 2018, she will be taking part in a ‘writing and publishing’ day at the National University of Ireland (Galway). Details to follow.

She will be attending the Bologna International Children’s Book Fair w/c 26 March 2018.

Contracts (Kcontractsevin Stewart and Jackie Wilson)

Kevin and Jackie are Greenhouse’s contracts experts.  Between them, they have 35 years’ experience in the negotiation of international publishing agreements and a deep knowledge of the evolving market factors that affect 21st century contracts. Their expertise comes into play once primary deal terms (advance, royalties and other significant points) have been agreed, working with our agents and with publishers to reach an optimum final contract for our authors.



Finance (Gafinancery Phillips and Lisa Darby)

Gary and Lisa form one of Greenhouse’s most crucial teams – Finance. Both have worked in the media, publishing and licensing industries for many years, and together they are responsible for coordinating all aspects of the agency’s financial affairs on behalf of our clients. This includes ensuring our authors are paid on time, reviewing and sending out royalty statements, and liaising with authors on issues related to overseas taxation.
