Thicker Than Water by Megan Collins

[Atria] In this “twisty, propulsive thriller” (Robyn Harding, internationally bestselling author) from Megan Collins, two sisters-in-law are at painful odds when the man who connects them—the brother of one, the husband of the other—is accused of a brutal crime. Julia and Sienna Larkin are sisters-in-law, connected by Julia’s husband and Sienna’s brother, Jason. More than that, the two are devoted best friends and business partners, believing that theirs is a uniquely unbreakable bond. To Sienna, her protective brother can do no wrong, and although Julia knows he’s not perfect, they’ve built a comfortable life and family together. Recently, Jason has been putting in long hours to secure a promotion at work, so when his boss is found brutally murdered—his lips sewn shut—the Larkins are shocked and unsettled, especially as local gossip swirls. A few days later, Julia and Sienna’s lives are upended when Jason gets into a car accident and is placed in a medically induced coma. Wo
