Beka's a 16 year old girl with the ability to speak to the restless
dead and an insatiable need for justice. Pounce is an extremely
powerful supernatural being, the earthly avatar of a celestial
constellation, who for its own reasons
walks the world in the form of a cat. Together, they fight crime!
Beka and her younger siblings were orphaned several years ago. Beka
feared they would be cast into the streets, but instead they were taken
in by a nobleman who was also the Lord Provost, in charge of the Dogs
who make up the city watch. Beka's brother and
sisters are being trained in useful trades that will allow them to
support themselves, but for years Beka's had her eyes set on being a Dog
and patrolling the streets of the slums they used to live in. She knows
that her ability to speak to the souls of the
recently dead and to other spirits of the city will help her in that
work, but she still has no idea what she's in for.
Together with Pounce, the magical black cat that has adopted her for
reasons of its own, she joins the Watch and is teamed up with two
legendary Dogs. It will take all of their power, skill and luck to
survive the mean streets of the city and bring to justice
the evil forces that are preying on the poorest and most helpless
citizens, the people no one cares about. No one but Beka and her
comrades.
There are three books in the series, all of them great reads. Start with Terrier, and I guarantee you'll want to continue on to Bloodhound and then Mastiff.
