Nexus Nine, Lowd Mary E.

Deep space, nine lives... Or maybe nine-hundred?

When a calico cat with a computer chip in her head--full of lifetimes worth of memories--sets out to uncover the mysteries of her distant past, she finds herself on a space station in a recently war-torn star system. Will her best friend from one of her previous lives as a dog still accept her? Can she make new friends with the local bird-like aliens, and how does her own past entangle with the history of a strange shape-changing insect seeking answers of zir own? As Mazel Rheun studies the local deep space anomaly, it becomes increasingly clear...

The answers lie on the other side of... NEXUS NINE.
