I love Locke & Key. This volume provides lots of background information on the creation of the keys and the birth of evil Dodge through the use of the clockwork key. Kinsey and Tyler travel back to 1775 to see the opening of the black door as well as the suffering of the Locke ancestors during the Revolutionary War. The contemporary Lockes also venture back to when their father and his group of high school friends attempted to acquire more demon metal for crafting a glamour key and ultimately invited their undoing. My only issue with this volume is that I missed spending time with Kinsey, Bode, and Tyler.
