A gripping debut set in modern-day Tokyo and inspired by a true crime, What's Left of Me Is Yours follows a young woman's search for the truth about her mother's life - and her murder.

In Japan, a covert industry has grown up around the wakaresaseya (literally "breaker-upper"), a person hired by one spouse to seduce the other in order to gain the advantage in divorce proceedings.

When Sato hires Kaitaro, a wakaresaseya agent, to have an affair with his wife, Rina, he assumes it will be an easy case. But Sato has never truly understood Rina or her desires and Kaitaro's job is to do exactly that - until he does it too well.

While Rina remains ignorant of the circumstances that brought them together, she and Kaitaro fall in a desperate, singular love, setting in motion a series of violent acts that will forever haunt her daughter Sumiko's life.

Told from alternating points of view and across the breathtaking landscapes of Japan, What's Left of Me Is Yours explores the thorny psychological and moral grounds of the actions we take in the name of love, asking where we draw the line between passion and possession.
