Gluck is co-chief of the literary department at uber-agency William Morris, along with Jennifer Rudolph Walsh.

Gluck attended Brown and worked as a researcher for New Yorker writer Ken Auletta after graduation. The connection paid off in 1984 when she joined ICM to work alongside Auletta's wife, Binky Urban. When Robert Gottlieb quit William Morris in 2001, Gluck was lured away from ICM and named co-head of William Morris's powerful literary department along with Jennifer Rudolph Walsh. Gluck has some big names on her client roster including Caleb Carr, John Berendt, Ann Coulter, and Kurt Andersenn. Not without her share of controversy, Gluck took the first submission from Harvard student Kaavya Viswanathan, author of How Opal Mehta Got Kissed, then passed it to Walsh, who sold the book to Little, Brown. Turns out that Viswanathan was less of a child prodigy than she seemed: Big chunks of Opal Mehta had been plagiarized, and the book was yanked from stores in 2006.

Gluck married husband Thomas Dyja in 1990. Dyja, then an editor at Bantam, has since become a successful novelist: He penned Play for a Kingdom (about two baseball-playing Civil War regiments who take a break from fighting to play a few innings) as well as Meet John Trow and The Moon in Our Hands.
