This volume contains 3 short pieces from the Locke & Key universe, photos and (brief) info on the inspiration of Locke & Key's setting in Massachusetts, and a photo and art gallery.

"Open the Moon": This is the highlight of the collection. It follows a sickly Locke boy (Ian) who lives in Keyhouse in 1912 and his father, Chamberlin, who wonders how he can use the keys to help him. As it takes place in the past, adults know about the keys.

"Grindhouse": I felt more take it or leave it about this one. 3 Québec(?) criminals break into Keyhouse and a bit of Home Alone story follows. Given the keys available, this can get pretty weird... Edit: I appreciated this story more after reading Small World and realizing Mary and Jean are the two sisters in "Open the Moon." I think Small Word is probably better to read before the stores in this volume.

"In the Can": This is almost two short to think much of. A pleasant surprise is that it features Tyler, Kinsey, and Bode (mostly Bode) from the main/original series. I think something about this went over my head as I don't know what I'm looking at in the last image (though I can guess what had just happened to whatever it is). I believe there are references to other IDW comics here. ( )

Always glad to get more stories from Keyhouse. I would love to see a long prequel series. ( )

I'd give it 2.5, if that were an option. The book's too expensive. I didn't mind shelling out money for the actual series. That's worth every penny. The same, however, is not true for Heaven and Earth. Bowled over by the Locke and Key series, I splurged on this addition as well. But there's nothing to it...

Of the three stories, Grindhouse was the best, following the creepy path that Hill and Rodriguez work well.
Over the Moon was a bit emotional, missing gore and violence, and hence, on a different scale from what readers are used to. Not bad, though.
In the Can leaves you foaming at the mouth that you spent time, money, and effort in reading even those few pages.

Don't buy. If bitten by the Locke and Key fan bug, beg, borrow, steal. But do not buy.

This graphic novel has a few short stories, mostly surrounding the house that was the centre of the Locke & Key books. Only one of the stories features the children in the main series. The last third of the book is mostly photos of the authors in places that inspired the fictional setting of the series.

I liked the short stories – the first one was the best one, in my opinion. The photos weren’t as interesting, but were ok and the book finished off with full page illustrations of the children in the series with other things in the background (the back of the book tells me these are additional covers). Overall, I’m rating it ok. ( )

There's not much to this. Three stories, one quite short, and a bunch of filler.

But that first story? Oh man, it's worth the price of the book all on its own. ( )
