The Lizzie McGuire actress, who recently appeared on Gossip Girl, has been out promoting the novel with a media tour, according to PerezHilton.com, reports the New York Daily News.
The book, written with Elise Allen and aimed at young adults, focuses on a young photojournalist, Clea Raymond, who's job takes her around the globe.
But after her father, a prominent surgeon, disappears during a humanitarian mission, Raymond's photos start changing and begin to focus on images of a strange man she's never encountered. The book weaves mystery, a dangerous love circle and a powerful secret into the plot, according to Amazon.com.
A review of the book on HollywoodCrush.mtv.com noted, "Think of it as 'The Time Traveler's Wife' starring a much-more-grounded version of Serena van der Woodsen."
When asked if the book might ever be adapted to the big screen, the reviewer replied in affirmation, "Because a novel this good is just begging for a big-screen adaptation. After gulping up 'Elixir,' I'm ready for another dose."
