Some of my favorite book logos for middle grade readers. These logos will change by either four color process or a standardized effect (4C printing over silver foil) throughout the series' publication.
The Dark Days of Supernatural (how it was first known) started as an ambitious author tour. Since its first inception in Winter 2011, the Dark Days tour has featured a wide range of authors each exploring their own supernatural or dystopian worlds. Enthusiastic readers return each season to blog, tweet, and attend author tours either in person or via live stream on Facebook. 

The logo and style guides changes to reflect the season.
