Day Zero by C. Robert Cargill

4.0

Pounce is a nannybot that looks like a tiger and he loves his charge Ezra but the day he finds his box in the attic is the first day he realizes that he won't be with Ezra for his entire life, one day he will grow up no longer need him. Unfortunely for Pounce his first existential crisis happens the same day world as everyone knew it ends.
The first part of this book where Pounce once he is freed and makes the conscious decision to save Ezra when the other bot in the house kills his parents the second she is freed slowly starts to build the angst and it just continues to escalate the whole way through the book. I wasn't certain I'd finish this because children don't interest me but this was a really good prequel to Sea of Rust. You can read them either in chronological order or publishing order(I did this) though I feel some things have a bit more impact when you read them in publishing order.
