3.5 stars, really.
Caveat—I know the authors and call them friends. But I did say I'd leave a reviews and not hold back any punches.
The Catalyst is a superhero novel on its surface. Some ordinary folk have powers and use them to protect their city (in this case, Pittsburgh, Pa.). In that sense, the book is average. The plot has a few twists and turns, but it's similar to many other origin stories as well as other first parts of trilogies.The protagonists are, for the most part, connected with the realm of higher education, and they all fit into some cliched slots—the bookish adjunct professor, the self-important part-timer who's in it just for the research, the devoted student with a crush on his professor, and so on.
Where the Catalyst works is behind the obvious story beats. Deep down, the novel is really interested in the plight of adjunct faculty, in the tarnished "glory" of the Golden Age of Pittsburgh, in poetry, and in localism and love of place (in this case, Pittsburgh and the surrounding region). All of this is coated in a superhero-flavored urban fantasy shell. I'll admit I was a little disinterested until about a third of the way in; by then, all of the tossed-off observations started adding up into something worthwhile.
I really dug how the characters, while flat in some ways, all had redeeming qualities as well as major flaws. And, with this in mind, none of the characters came off as boring anti-heroes, either. There were a few points where I wasn't sure who the "good guys" were.
One thing I did not dig, at all: the "male gaze" rears its ugly head a few times, and its pretty sophomoric.
Still, the interesting aspects far outweighed the bad ones. And this is a debut novel, so I'm willing to give some slack in that regard.
