Bestselling writer Gillian Flynn is staying at Random House. The author of the current hit Gone Girl has signed to do another book with Crown (her current publisher), along with a young adult novel for the house's Delacorte Press imprint.

Flynn has already published three novels with Crown – before Gone Girl was Sharp Objects and Dark Places – and has another under contract, which is scheduled for 2015. Molly Stern, senior v-p and publisher of Crown, inked the world rights adult deal with agent Stephanie Kip Rostan at Levine Greenberg Literary. Lindsay Sagnette, a senior editor at Crown, will be editing the novel.

The YA novel was acquired by Beverly Horowitz, v-p and publisher of Delacorte, who also took world rights. Rostan also brokered this deal, and Krista Marino, executive editor at Delactore, will edit. RH has not set a pub date for the adult novel or the YA one.

RH said that Gone Girl, which was published in June and recently optioned by 20th Century Fox, has sold nearly 2 million copies to date.
