William Morris Endeavor has acquired the Rabineau Wachter Sanford & Gillett (RWSG) Literary Agency.

RWSG is a boutique agency based in Los Angeles that represents a number of authors and TV/film writers and is known, in particular, for handling the dramatic rights of a number of bold-face literary names. Through the deal, principal RWSG agents, Sylvie Rabineau and Jill Holwager Gillett, will join WME's Book to Film/TV division as co-heads.

Jennifer Rudolph Walsh at WME said the deal "builds upon WME’s commitment to great storytelling and our love of books." Walsh added that Rabineau and Gillett will strengthen WME's co-agent business, helping the agency bring more literary projects to Hollywood.

RWSG, founded in 2000, has been involved in book-to-film deals behind such film adaptations as The Girl on the Train, Diary of a Wimpy Kid and The Snowman. Some of the authors whose dramatic rights it represents include Megan Abbott, Roxane Gay, Sara Gran, Paula Hawkins, Denis Johnson, Jo Nesbo, Tom Perrotta, Gary Shteyngart, Olen Steinhauer and Elizabeth Strout.

In addition to Rabineau and Gillett, RWSG's Geoffrey Sanford will be joining WME, continuing to oversee his client list of New York-based writers. Liza Wachter, who has been at RWSG for 16 years, is leaving the company.

In a release about the acquisition, WME said the deal speaks to the agency's "commitment to support and grow relationships with independent publishing agents."
