The #1 New York Times bestselling author Maggie Stiefvater (The Raven Cycle series) and artist Morgan Beem unearth the primal power of memory and how it twists the bond between two brothers. Twins Alec and Walker Holland have a reputation around town. One is quiet and the other is the life of any party, but they are inseparable. For their last summer before college, the two leave the city to live with their rural cousins, where they find that the swamp holds far darker depths than they could have imagined. While Walker carves their names into the new social scene, Alec recedes into a summer school laboratory, because he brought something from home on their trip—it’s an experiment that will soon consume him. This season, both brothers must confront truths, ancient and familial, and as their lives diverge, tensions increase and dormant memories claw to the surface. Swamp Thing: Twin Branches is a story of shadows, both literal and imagined—and those that take form and haunt us.
