The premise, in the publisher's words
Halloween is off to a rough start. The plan was simple: get ready, grab your friend, and hit the party. But when the mayor turns up dead in a back alley, "simple" is officially off the table. Meet Sunny Summers. She's got a moody attitude, a wardrobe that's 99% black, and zero interest in being a hero — or anything positive really. She takes out her mood swings on her AI companion Cogs, a lovable penguin robot. They are, without a doubt, the worst duo to ever be tasked with solving a murder. But sometimes, you don't get to choose your adventure.
