This was a novel by (probably) a popular author, but my memory is a bit faded on this one. Following is what I remember about the novel. I'll be very glad if anyone can help me identify the novel.
- Set in a dystopian society where the "normal human beings" are confined to forts and have to stand guard against creatures that run wild.
- It's dangerous to go outside the fort as the (probably) white monsters attack and kill humans with their claws. The monsters are likely white, soft, and furry with sharp claws.
- Something (water, electricity, etc.) inside the fort fails and a party has to be formed which takes an excursion to a (generator, water tank, etc.) station where they've to fix something. Many don't survive the expedition as they're attacked by the creatures.
- There was a small love story arc between one of the characters (who's also a part of the expedition) and one of the inhabitants of the fort.
- Likely turns out that the white monsters are a result of a (military) experiment gone wrong where erstwhile humans are changed into this white monsters. I vaguely remember a character (likely named B-o-b-c-o-c-k ) recollecting his past life when he was a human (and a few letters of his name).
- Likely one of the white monsters breaches the fort. But he was a friend/someone known so not much damage is done.
Not sure how the story ends. It's also a bit likely that I'm mixing up stories. It's a rather recent novel -- not too (> 20 years) old.
