Here is the cover to Locke & Key: Keys to the Kingdom # 1, which features a standalone story called “Sparrow.” With the exception of the last two issues, all of the stories in Keys to the Kingdom are standalones. The issue will be on sale on August 11th, 2010.
According to the writer, Joe Hill, the audience doesn’t need to already be familiar with the series to jump in and enjoy. Every issue will also introduce a set of new keys (again, except for the last two). And when Keys to the Kingdom wraps up, Locke & Key will be moving into the final stage of the larger story.
The plan is for just two more books after this one, and then the door will close on Locke & Key.
