The truth could be a father’s redemption—or a daughter’s destruction.

Mercy Gale has spent her life in the shadow of a legend. Her father, E. Thomas Gale, was once America’s most celebrated defense attorney—a legal icon whose high-profile trials captivated the nation. Now, dementia is claiming his brilliant mind, and he’s retreated to a remote island on Lake Michigan to live in seclusion.

But a convicted killer from her father’s past contacts Mercy with a threat to expose Thomas’s long-hidden secrets. Mercy finds herself drawn into a murder case that ruined two families, including her own. Jeremy Holt was her father’s last client in the only trial he ever lost. For fifteen years, Jeremy has insisted he was innocent of his sister’s brutal murder. And Mercy has just found the first piece of evidence that suggests he might be telling the truth.

As she digs into the past, Mercy uncovers a trail of corruption, betrayal, and buried secrets no one wants brought to light. But nothing prepares her for the most devastating question of all: Was her father’s trial loss the result of a failing mind—or was he part of something far darker?

Either answer could destroy his legacy—and Mercy along with it.

Thicker than Water is the first gripping installment in the Mercy Gale Mystery Thriller Series. Perfect for fans of Karin Slaughter, Lisa Scottoline, and John Grisham.
