The Hat Club

The Evolvit Smart 3D Printer/Scanner/Copier is the next step forward in cloud manufacturing. Besides working as a normal 2D scanner and printer, it can also scan and print 3-dimensional objects in a variety of materials including food and human cells, storing the resulting files on the AtomCloud so that the entire network of Evolvits across America and the UK can access them. But what happens when three friends scan a drawing of an impossible 4-dimensional object? The three McBucky-Mayer Gigacorp employees - marketing writer Eve, materials scientist Desta, and software engineer Thanh - try this experiment one afternoon with disastrous repercussions: mobile phones create havoc, a giant pastry takes its revenge, people vanish into thin air, and an entire city is driven to a sexual frenzy.
And Eve, Desta, and Thanh develop their own strange deformities which prompt them to start wearing hats. As the crisis escalates, the three are sent from the McBucky-Mayer headquarters in Los Angeles to the Yorkshire city of Sheffield to find out why recently-built buildings are rapidly deteriorating and brand new structures, including a centuries-defunct castle, have popped up overnight. Amidst suspicions of a terrorist plot the trio of friends finally discover the real truth which, surprising as it is, changes each of their lives.
