I wrote a hard SF novel about a physicist who won't accept that information can be destroyed and I'd like honest reactions

Hi everyone. I’m Carlos, an engineer, but writing is my real passion.

Here's the premise:

Ethan lost his wife. To cope, he clings to a physical law: information is conserved. Nothing is ever truly destroyed, just scrambled and unreadable. It's his only shield against the idea that she's gone forever.

But then, something begins erasing the universe, and that law breaks down.

I wanted to write a book about grief and fatherhood told through physics, rather than a physics story with grief bolted on.

If you're into the cold rigor of Blindsight or the philosophical patience of Anathem, this might be right up your alley.
