A lover of all things fairytale, Caroline Derlatka has always believed in magic. She grew up creating fantastical worlds in her head—places filled with unicorns that would give her rides over ribbon rainbows, giant hares that would lead her through cotton candy clouds, and mermaids that would swim with her into the deep. She is a constant dreamer with a million ideas and about eight hundred big plans. After living in Los Angeles for twenty years, she now splits her time with her husband, son, and cat between the shores of Flathead Lake, Montana, and the green hills of Nashville, Tennessee. When You Open A Book is her debut publication. To find out more about her other projects, which all benefit various charities, visit her online at carolinederlatka.com.
