If you're a big fan of the superhero genre, you'll probably like this, but I'd otherwise have given it three stars. It's well written enough, but it doesn't really bring anything new to the table, and it felt rather like
Wild Cards-lite. The authors try to build the entire world and its history up all in one volume, which is a daunting task when you're simultaneously introducing a global threat everyone has to fight. The result is a story that pretty much resembles a
Champions (superhero RPG) campaign. It's fun, and since it's available as a free podcast, you can't go wrong by trying it out, but I'm not feeling compelled to immediately listen to the next book in the series.
