Young adult novels heating up the charts
Publishers, stores embracing trend
It all began with the “Twilight’’ series, which has the first of its two final movie installments, “The Twilight Saga: Breaking Dawn - Part 1,’’ hitting movie theaters this weekend. The book ignited a publishing industry trend that continues to see adults purchasing books written for teens. Young adult books are no longer for kids alone - and, as a result, sales are often out-pacing grown-up bestsellers, sometimes by millions.
