Worlds Colliding (Supernatural) Book Six

Catty and Dean Winchester and Ness Singer have been out of the life for a year now.
Catty had gone to her old flame, Brett Blake, up in New York, and made friends with his family. Became a cook at a restaurant and babysat Brett's sister, Sarah's, baby Abby.
Dean and Ness had remained in Sioux Falls. Dean became a construction worker. Ness still works at TJz.
But everything changes when their past comes back to haunt them, and Sam Winchester, who they thought to be dead, brings them back into the game.
But Catty only comes back because of a disaster that happens, that rattles her to the core, because she blames and hates herself for it. It's a different side of Catty that we haven't seen before.
And Castiel the Angel is acting strange. Unlike himself. Sometimes there's a switch in his brain that can flip whenever.
And Octavia the Angel is back to full power, but she still feels as strongly as a human does due to her human experience, no matter how short. And even though she knew something was wrong with Sam because they've gone closer, she'd never guessed that he'd left behind his soul in Lucifer's cage with Lucifer and Michael.
Everything is about to shatter...
For all of them.
You can't outrun your past.
