By day, Ida is a quiet, standoffish maid in the employ of spoiled Lucinda Belmonte. By night, she is the infamous sneak thief known as the Rat Prince, terrorising the wealthy inhabitants of Loxport; especially Lucinda's lecherous suitor, Lord Devon Casterbury.

Soon the boundaries between her dual lives begin to blur, as her mask begins to drop around a delightful waitress and a charming jeweller who both insist on befriending Ida. All the while she is thrust into a conflict surrounding new and dangerous materials that could upend the order of the city, land her behind bars or worse: in Lord Casterbury's employ.

A thrilling romp through the Steampunk city of Loxport, Clockwork Magpies is a story of found family, crimes plotted over tea and scones, and the sinister power of glowing gemstones.
