The apartment had no smell anymore. That was the first wrong thing.Blackberry has spent her whole life inside — four years of windowsill watching, familiar scents, and the steady routines of the family she belongs to. On moving day, a door is left open one beat too long. She slips through. The truck pulls away. The building goes dark. And a house cat who has never set paw on a sidewalk finds herself alone on a dense city block with nothing but instinct and the long summer stretching ahead of her.4th Street is not kind to newcomers. There are dogs on patrol, hawks circling overhead, raccoons guarding the dumpsters, and a territorial tomcat named Bullseye who makes it clear that every good shelter on the block already belongs to him. Blackberry must learn the street the hard way: which alleys are safe, which humans leave food out, which sounds mean danger, and which silences mean something worse.But the street holds surprises too. One by one, Blackberry encounters a group of animals as mismatched and unlikely as any family could be: Volkswagen, a rabbit whose frantic energy picks up threats before anyone else; Coffee, a parrot whose constant chatter changes quality when something is wrong; Lucky, a small dog who adopts Blackberry whether she likes it or not; and Magpie, a sugar glider who sees everything from the rooftops — when he bothers to wake up.As summer turns to fall, a new predator arrives on the block. One that is faster and smarter than anything Blackberry has faced. She cannot survive it alone. And the only animal who might stand with her is the one who has spent the whole summer trying to drive her out.The Black Cat on 4th Street is Book 1 of the Black Cat on 4th Trilet, a middle grade series about survival, belonging, and what it takes to make a street your own.
