“Honestly Shadow Avengers is a pure delight. It will definitely be enjoyed by fans of the books and showcases the wonderful possibilities the Crisis Protocol tabletop game holds. Not to mention we have a wonderful cast of characters.”

“This reminded me, in a very good way, of a 90’s Marvel comic series called Secret Defenders. It was a quick read that I would recommend to most Marvel fans (old or new).”

“There’s a way Carrie writes, that brings the superheros and even Villains to life. Honestly I can’t explain it, but she didn’t miss in the personality department for each characters.”

“Shadow Avengers is a good follow-up to Target Kree, a book that took the small hints and promises at the end of that book and gives readers something exciting as the pay-off. It manages to pack in the action, gives just enough mystery to keep readers guessing what might come next, and features some great depictions of some of Marvel’s biggest characters.”

“The plot is tight and well paced and thought out. We slowly learn what is happening for alternative perspectives and to see how it all fits together with the Master’s plan is fantastic.”

“Carrie Harris has a good handle on each of the characters, and she ensures each one gets equal exposure: something which is not always easy in a multi-character story.”
