It's Lila Pettitt's first day as the youngest female judge the British court system's ever seen. Fiercely ambitious, Lila's determined to dispense real justice, not just obey the letter of the law. But a shocking betrayal by her mentor, Will Carlisle QC, makes Lila realise that the legal world she's devoted her life to is far murkier than she ever could have imagined.
