At first, the death appears to be an accident. But then Kat discovers an infinity symbol branded onto the dead woman’s abdomen. She’s convinced there’s a vicious killer at large. Still juggling her turbulent private life with her professional duty, she begins to dig into the victim’s past. There, she uncovers shocking secrets and several potential suspects.
