Here are a few books that were handpicked by our content managers:
My pick (CLZ Taco) this week is: Justice League Unlimited #20F. Another Supergirl cover releasing this week, It will never stop! And a Bilquis Evely cover no less. Lex Luthor and the Dark Knight are the heart of the mystery surrounding Brainiac Queen’s return.
My pick (CLZ Rowdy) this week is: Hellboy and the BPRD: The Monster of Nivola #1A. Rumors of a monster bring Hellboy to a nearly abandoned town in Sardinia, where the search for the creature leads to a local abbey with a shocking secret of its own. What trouble will it bring Hellboy? Written by Christopher Golden & art by Daniele Serra!
My pick (CLZ Justin) this week is: Absolute Wonder Woman #21B. A new chapter in the Absolute Wonder Woman saga, this week a new 2 part story arc titled: Friends & Neighbors. The cover I picked, connects to Absolute Superman #20 & Batman #21. They’re going to look on my wall!

Two nice improvements for CLZ Web in one go. First, you can now add a cover thumbnail as a column in your List View. Next to that, we spent some time improving the keyboard support in the Edit screen.
On top of that, we’ve now also added the possibility to install CLZ Web “as an app” to your computer.

NCBD! Yes, another Absolute title that takes the crown for being the most populair comic this week. It’s Absolute Batman #21, this time with 107 variants! Amazing Spider-Man #31 should be an interesting issue too, due to what’s been going on with a certain Cormac Crane… And if that’s not all, Something is Killing the Children is back with #48. Here are a few books that were handpicked by our content managers:
My pick (CLZ Taco) this week is: Lobo 4. I’m currently buying anything Supergirl related. Hey, no need to judge me. Lobo and Supergirl on a date? This story will be told in another perspective inside of the Summer of Supergirl Special. This one should be more fun though.
My pick (CLZ Rowdy) this week is: Concrete: Stars Over Sand #1. Concrete wandering across the desert, Lost. Larry and Maureen are frantic. Will they find him in time? Found out here!
My pick (CLZ Justin) this week is: Hellboy in Love: Obsidian #1. Hellboy and Anastasia playing Indiana Jones in a tomb with monsters? Sold

NCBD! Absolute Catwoman has arrived! With 73 variants nonetheless. Yes, our content managers are still doing okay. Image is releasing Youngblood’s anniversary issue 1000. And Marvel’s Armageddon event starting off today! Here are a few books that were handpicked by our content managers:
My pick (CLZ Taco) this week is: Supergirl 14E. The search for Supergirl! Lena Luthor searches for Supergirl before it’s too late for the bottled city of Kandor. Nothing can stop Black Flame as she continues to be a threat to the city. Love the cover by Jim Lee, this in my opinion is one of the best Supergirl movie variants.
My pick (CLZ Justin) this week is: Avengers: Armageddon #1. Red Hulk trowing a rampage across the world, Avengers, the Fantastic Four, Wolverine and more are here to stop him but who will survive?
