The days grow shorter and the nights colder, but for Millie Lucas and her wealthy protector Benjamin Castle, things are about to heat up.
The trouble starts on the road when they nearly have a collision with thunder, the name for cars in the strange world in which Millie finds herself. The driver is unscathed, and Millie finds herself intrigued by the vehicles. She discovers that Ben is also an enthusiast, and together they delve into the world of thunder racing.
Unfortunately, trouble is never far behind and they find themselves neck-deep in charms, talismans, and witchcraft, all carried by the thunder drivers to ward off a string of bad luck that stalks their members. Ben smells something fishy about the whole thing, and they delve deeper into the mystery only to find that his suspicions are more than just true. They're deadly.
As if that wasn't enough, Millie finds herself the talk of the town when an exclusive book club asks her, as the intimate companion of a nobleman, to join their group. A simple 'no' is never accepted, and she is thrown into a perfumed jungle of secrets, lies, and a petty jealousy that may threaten the very life of her newest friend.
Magic and mayhem collide as the lovers wade through the mysteries of the city and dig up the ugly intentions of those who would cultivate chaos, and where a single misstep could spell their doom.
