Los Angeles, May 12 (IANS): Actress Julia Roberts will star in a film adaptation of best-selling novel "The Bookseller".

Crystal City Entertainment has optioned Cynthia Swanson's book. The story follows a woman in the 1960s who must reconcile her reality with the tantalising alternate world of her dreams, reports hollywoodreporter.com. 

Swanson's book, which first hit the shelves in 2015, follows Kitty Miller, a single woman who runs a bookshop and finds herself living out an alternate life -- one in which she is married to the love of her life and has beautiful children -- in her dreams. The lines between her real-life and dream life begin to blur, and she must figure out what is real and what is imagined. 

Roberts will also produce with partners Lisa Gillan and Marisa Yeres Gill through their Red Om Films banner, along with Crystal City's Jonathan Rubenstein and Ari Pinchot.

Roberts's recent credits include Jodie Foster's "Money Monster" and ensemble film "Mother's Day". She will next be seen in "Wonder with Owen Wilson".
