Sarah founded Greenhouse when she moved to Northern Virginia in 2007 after a long career as a UK children’s publisher, working with many internationally celebrated authors. After a decade in the States, she is now back in the UK, but regularly spends time in New York (when Covid isn’t stopping her flying!).
As Publishing Director at Macmillan Children’s Books UK (until 2007) Sarah was part of the team that published market-leading authors such as Judy Blume, Philip Pullman, Sharon Creech, Gary Paulsen and Julia Donaldson, and for many years she edited authors as varied as Meg Cabot and Geri Halliwell of the Spice Girls.
Sarah has been an editor most of her life but also has considerable experience in management, contract negotiation, marketing and rights. Many years spent living in both the US and UK have given her an unusually transatlantic view of the children’s books industry, from both sides of the desk. A member of AALA, Sarah has crossed America and Europe talking about children’s books and writing craft, and she loves to inspire and encourage new authors and share all she has learned about the industry. She says, ‘Everything you need to know about Greenhouse is in its name.’ Follow her on Twitter at @SarahGreenhouse and discover more about her taste on her Publishers Marketplace page.
Chelsea Eberly represents authors of middle grade, young adult, graphic novels, and women’s fiction, as well as illustrators who write picture books. As a former Senior Editor at Random House, she edited the Newbery Medal winning When You Trap a Tiger by Tae Keller as well as award-winning and New York Times bestselling authors such as Tamora Pierce, Leigh Bardugo, Marie Lu, Sarah J. Maas, Mark Siegel, and Kim Johnson to name only a few. She has a deep understanding of how publishers think and is an expert advocate for her clients. Chelsea is also a Publishers Weekly Star Watch Honoree, which recognizes “the rising stars of the US publishing industry.”
A Midwesterner turned New Yorker, Chelsea regularly presents at writing conferences across the country and enjoys teaching craft. Follow her on Twitter at @chelseberly and discover more about her taste on her Publishers Marketplace page.
Kristin Ostby represents authors of middle grade and young adult fiction, as well as picture book author/illustrators and select adult fiction. She is primarily seeking tightly written, tightly plotted, fast-paced commercial middle-grade and young adult fiction—adventure, mystery, and contemporary humor—as well as young adult romance.
As the daughter of a librarian and a businessperson, it’s really no wonder Kristin wound up in the book biz. Kristin moved from Michigan to New York to begin her life in publishing at Penguin Random House, and after sixteen years as a children’s book editor (and freelance writer on the side), she rose to become a senior editor at Simon & Schuster Books for Young Readers. Kristin has had the joy and pleasure of editing children’s book legend Tomie dePaola; New York Times bestselling authors like Stuart Gibbs (Spy School) and US soccer star Alex Morgan (The Kicks); and award-winning creators including Daniel Miyares (Float), Jessica Lawson (Nooks & Crannies), and Heather Vogel Frederick (The Mother-Daughter Book Club). She also edited the mainstay bestseller I Dissent: Ruth Bader Ginsburg Makes Her Mark by Debbie Levy and Elizabeth Baddeley. Kristin loves guiding authors and illustrators toward their best work and advocating for them in service of building successful, sustainable artistic careers.
Kristin lives in Brooklyn, New York. Follow her on Twitter at @kristinostby and discover more about her taste on her Publishers Marketplace page.
The people who support the work of the Greenhouse agents (new photos to follow when Covid regulations allow!)
Rights People is a dedicated children’s rights-selling business – a team of experts in the field: Charlotte Bodman, Alexandra Devlin, Amy Threadgold, Harim Yim, Claudia Galluzzi, Jodie O’Toole, and Hannah Whitaker (who sells adult rights). Between them, Rights People have many years’ experience and a huge network of international contacts. They attend Bologna, Frankfurt and London Book Fairs, and undertake territory-specific selling trips around the world at other times of the year.
Rights People is Greenhouse’s sister company and represents all the agency’s foreign rights. This gives Greenhouse an exceptionally cohesive presence around the world and a truly global reach. Here, they’re photographed in a brief lull at Frankfurt Book Fair! You can read more about them here.
Contracts (Kevin Stewart, Jackie Wilson and Charles Devine)
Kevin, Jackie and Charlie are Greenhouse’s contracts experts. Between them, they have many 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. You can read more about them here.
Finance (Gary Phillips and Hiwot Beyene)
Gary and Hiwot 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.
