This book series is based on The Partridge Family tv show.  Shirley Partridge, a widow with five children turns her family into a band, and they travel around to singing engagements in a bus painted with psychedelic designs, having adventures along the way.  Their business manager is Reuben Kinkaid.  He lines up singing engagements for them and helps make travel arrangements.

The five children are:

Keith – The oldest child, a teenager.  He plays guitar for the band.

Laurie – Next oldest, a teenager.  She sings.

Danny – Ten years old.  He also plays the guitar and often has his mind on business.

Christopher – Eight years old.  He plays the drums.

Tracy – The youngest.  She sings.

The family also has a dog, a small poodle named Simone.

Many number of the books in the series are mysteries, which is different from the original tv show.  The books in the series were written by different authors, although not as many as it appears because Vance Stanton was a pen name used by Michael Avallone.
