Long Bright River Summary: A Sister’s Search

Liz Moore alternates between the present and the past. In flashbacks, Mickey and Kacey are raised by their grandmother Gee after their mother dies of an overdose.

Their father vanishes from their lives, or so they believe. Gee is cold and strict. The sisters join a Police Athletic League program, where a teenage Mickey becomes attached to an older officer named Simon Cleare. Kacey drifts toward drugs.

After Kacey’s first overdose, Mickey turns to Simon for comfort.

Their relationship becomes secret and sexual. Gee refuses to help Mickey attend college, so Mickey joins the police force. She buys a small house in Port Richmond. Kacey cycles through addiction and incarceration.

When Kacey relapses after living with Mickey, Mickey forces her to leave.

Soon after, Kacey becomes pregnant with Simon’s child. Mickey agrees to a secret arrangement. Simon gives up parental rights and promises to fund the child’s education.

Mickey takes custody of the baby, Thomas, and raises him as her own. Kacey returns to the streets. Liz Moore uses this secret to deepen the tension between the sisters.

Five years later, Kacey is missing.

A serial killer is strangling sex workers in Kensington. Paula Mulroney, Kacey’s childhood friend, tells Mickey that a police officer is demanding sexual favors. Mickey reports this to Sergeant Ahearn, who dismisses her and reports her to Internal Affairs. Mickey is suspended. Paula is then murdered.

On Christmas Day, Mickey discovers hidden letters and child support checks from her father in Gee’s house. Gee had lied about his abandonment.

Mickey finds her father, Dan, sober in Wilmington, Delaware. He has taken in Kacey, who is pregnant. Kacey later tells Mickey that the serial killer is Eddie Lafferty. He used his badge to exploit victims.

Kacey lures Lafferty to an abandoned cathedral.

Mickey follows. Lafferty attacks her and takes her gun. Dock, Kacey’s former boyfriend, disarms Lafferty and returns the weapon to Mickey. Police backup arrives and arrests Lafferty. He is connected to the murders, including the first victim, his ex-wife Sasha Lowe Lafferty.

After the arrest, Mickey resigns from the police force. She leaks details of police sexual exploitation to public radio. She takes a job at her uncle’s car dealership.

Kacey, now clean for over six months, visits Thomas every Sunday.

The novel ends with Mickey, Kacey, and Mrs. Mahon visiting Kacey’s newborn daughter in the hospital. They watch as a withdrawing newborn receives care, a final image of the cycle of pain and survival in Kensington.
