Blood Sugar

A New York Times Best Thriller of the Year

"A fascinating story, wicked sharp writing, and an unforgettable narrator." —Samantha Downing, author of My Lovely Wife

She's accused of four murders. She's only guilty of three.

"I could just kill you right now!" It’s something we’ve all thought at one time or another. But Ruby has actually acted on it. Three times, to be exact.

Though she may be a murderer, Ruby is not a sociopath. She is an animal-loving therapist with a husband, Jason, whom she adored. But detectives at Miami Beach Police Department are eager to uncover why so many people have died within her arm's reach.

When we meet Ruby, she is in a police interrogation room, accused of Jason's murder—the one murder she did not commit. As she undergoes questioning, her mind races back to all the details of her life that led her to this moment, and to the three dead bodies in her wake. Because while she may not have killed her husband, Ruby certainly isn't innocent.
