Candy by Lavie Tidhar
In a city where all chocolate and sweets have been banned, Nelle Faulkner is a 12-year-old private detective looking for her next client. So when notorious candy gangster Eddie de Menthe walks into her office (her dad’s garden shed) and asks her to find a missing teddy bear, Nelle takes the case. But as soon as the teddy turns up, Eddie himself goes missing.
