Worm- Web serial by J.C McCrae. It can go in action, sci-fi and maybe a little bit of horror is in there too.
For those not familiar with web serials, the first thing you should know is that Web serials tend to be incredibly long. Worm is no exception. To quote the home page that gives a quick summary of the book. "It totals roughly 1,680,000 words; roughly 26 typical novels in length (or 10-11 very thick novels)." So if you give it a try, be prepared to stick through a lot.
So, let me now summarise the serial. It is about an introverted young woman named Taylor who has the capability to control bugs in this superhero filled world. The story begins with her first attempt to take down a bona fide badass of a villain, the notorious leader of a local gang, because she aspires to be a hero. Shit goes down, she proves how bugs can be scary and the circumstances evolve. The story follows Taylors induction and adaptation to the Superpower community in the main setting of Brockton Bay. McCrae uses Taylors perspective to explore morality in this world and explore what a society would be like in such a world. If that doesn't interest you, bear in mind, Taylor does not start off on the good guys side.
Now, for what makes this serial shine. Power scaling and action. The writer is fantastic at choreographing action scenes and the unique set of powers in the very, very large cast is used very creatively. In specific Taylor's capability to control bugs, something that seems insignificant, is proved to be something incredibly versatile and downright scary. A character who has very good intuition as a superpower is actually one of the most feared characters in the series.
Then there's the threats. The characters and monsters that are literal walking disasters. The Endbringer battles are some of the most harrowing scenes I've read. If you think Game of Thrones is liberal with character death, then Worm takes it up a notch because no one is safe in these fights. In the first Endbringer battle in the series, it has been said that McCrae simply rolled dice to determine if a character survived.
One final note about the finale. No spoilers, don'tchu worry child. but I like to think a finale is one of the bigest selling points of a story so it needs to be discussed. The finale is, well, it's built up for a long, long time. It takes a while to get there and it drags as it approaches. However, the final arc of the series, holee shit, the final arc is every bit as climactic as you could want. It's orchestrated perfectly, every faction plays it's role and the Big Bad is no joke. The epilogue alone leaves you with a little sigh of satisfaction.
So, go read it, Worm is good.
Next, from the same Author, the second Webserial to their name, Pact. This is a Horror/Action story without any doubt.
This story is quite long but not to the extent of Worm, much smaller. In case you wanted something a little less. This story follows Blake Thorburn, Blake used to be a part of a very unhappy family constantly vying for the grandmothers favour so they can inherit the Thorburn estate. However, the Thorburn estate and the surrounding area is not normal by any means and Blake finds himself plunged into a goddamn terrifying, if ordered, world of every monster under the bed.
The high points of Pact aren't as evident for me as they may be for others but I can appreciate them. For one, McCrae is god damn fantastic at writing horrific creatures of the beyond. Some of these things are just shy of being Eldritch abominations. When McCrae wants to be terrifying, they are fucking scary.
Another pro of the series was touched on in my revew of Worm. McCrae is very good at Choreographing action scenes and whilst action isn't quite as prevalent, this choreography actually transfers very well into interactions. Due to the nature of monsters, these interactions are as close to verbal sparring as you can get so this skill is used very well.
There is a glaring Con of the series and that is just, it's depressing as all hell at times. Naturally it's not meant to be bright and happy but the things that happen to each of the characters is pretty devastating. The shit Blake has to wade through is insane and barring a grand total of two characters there's practically no one else going through it with him. Along side him yes but not with him. The plus side of this is that there are some huge crowning moments of badass.
The finale for Pact. McCrae does some pretty good finales in my eyes. The consequences may not be the best but dammit all if it wasn't awesome. You know one of those crowning moments of badass? All I'm going to say is: Defenestration.
So there's two of my reviews and I've got many, many more to go.
