I got this for my birthday a few years ago from my mother, who noticed it was on my wishlist.

Let's just say, off the bat, that "Complex" by A.D. Enderly is complex in itself, but once you get your head around the ambitious science fiction fantasy world - which still didn't quite make full sense to me as I had a hard time imagining this world - it became gripping, exciting, and definitely all comes to a head, at the very end, and I was fully involved as it got progressively tense.

Various characters and storylines flow throughout, with the main plot of Val trying to find her sister who was kidnapped from their flat, right before Kat's eyes. Her mission to find her spans diverse and complex landscapes and areas.

I was invested in a few of the subplots, such as the man who was offered a better life in a Complex in return for a cure for his wife - who still passes away and he's essentially stuck inside one of the Complexes, and I was interested in Kat's storyline at the hospital.

I was somewhat disappointed with the ending, it became too quick-paced and it was almost as if the author forgot how gripped the reader was going to be, and I was trying to read the words quickly enough, but in doing so I missed some things and had to read back over the paragraphs to understand - more description of the world and those action-packed scenes would have fleshed it out a lot more.

Interesting, and truly unforgettable, "Complex" is a brilliant piece of work and although I wanted to fully understand and visualise this world, the author managed to give the readers intertwined subplots and exciting characters in a brilliant dystopian world.

This marks A.D. Enderly's debut novel. I'm eager to see what he releases next and I'm sure I'll be just as invested in the storyline as I was with this one.

Blurb: The sky rains red, the poor are forgotten, governments have failed, and corporations have grown into mini nation-states called Complexes, where people flock to receive the security, shelter, and purpose the outside world can't provide. The only payment required, buried somewhere in the twenty-thousand-page Terms of Service, is their freedom.

Now just sign on the dotted line...

Orphaned after her father's death, 18-year-old Val's focus is to protect her younger sister Kat and heed her father's final wishes: Never, ever join a Complex. Stay away from them, at all costs, he demands.

But staying away becomes impossible when Kat is abducted, sparking a hunt through a violent megacity primed for revolution, where Val eventually discovers her sister's disappearance is just a smokescreen. Beneath it lies a motive darker than death and broader in scope than a few lives.

As Val and her allies uncover the truth, they're confronted with a terrible choice - save Kat, or save humanity?
