The 96-page book will be published by Little, Brown and Co. and will feature images of photos of heart-shaped objects Barrymore has snapped during the last decade.
"I have always loved hearts," Barrymore told E! News. "The way that one continuous line accomplishes the most extraordinary thing -- it conveys love. Hearts are my beacons. I love them man-made and natural, young and old.
"Whenever and wherever I see the heart shape, a smile spreads across my face. The heart has an unbeatable romance when you discover one where you least expect it."
