17 Books to Read If Your Obsession With Big Little Lies Is Going Strong

A friendship between childhood pals Annie, Jake, and Mason gets more and more complicated in Ursula Hegi's The Worst Thing I've Done. After years of close friendship, Annie's parents die on the night she and Mason tie the knot, and they — along with Jake — decide to raise her newborn sister, Opal, together. This arrangement obviously results in lines (and morals) getting a little bit blurry, eventually leading to shocking consequences that none of them could have ever seen coming.
