When I first read the 'schtick' for Titan of the Stars, I was completely hooked: Alien meets Titanic. That could either be completely terrible, or excitingly great.
The beginning was a bit slow-going due to the need to describe the world, the situation, and the people involved, but as I continued, I was greeted with the delightful beginning of deepening anxiety where a sci-fi novels descends into the chaos of being hunted by something not quite human. I feel as though the gore was limited, which isn't quite a bad thing, but if you're looking for worse you may be disappointed.
The connection to the Alien franchise is fairly blatantly obvious, which isn't a bad thing since it claims to follow similarities to the series. The Titanic connection is easily notable: big ship intended for the fanciest of pants, while the 'indentured' workers have to remain as out of sight as possible to not scar the vacation of the rich. The classism and socio-economic standards are all but highlighted with our two main characters: Dominic Ruebens, the adopted son of an ex-parliament member and co-creator/designer of the giant ship Titan, and Celeste Sparrow, an engineer from the portion of Canada that had undergone a natural disaster.
If you're interested in a practical homage to Alien with more than one human survivor (plus cat), and an ending open enough to potentially go the route of Aliens/Alien 3, then I highly suggest giving this book a try!
Would rate this Five out of Five Jonesy the Cats!
