Thicker Than Water: A Novel

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. Worse, the police arrive with news that he's the prime suspect in the murder investigation. With Jason unable to respond--and with Julia and Sienna working to clear his name--the two women find their friendship threatened for the first time: Sienna staunchly maintains her brother's innocence, but as their investigation uncovers a complicated web of secrets, Julia is less sure she's willing to defend her husband.

With her signature "moody and atmospheric" (USA TODAY) writing, Megan Collins has crafted a rich, gripping story that explores just how fragile our closest bonds can be.
