Amy Sherman-Palladino is plotting a new family affair for HBO.

 
According to The Hollywood Reporter, the "Gilmore Girls" creator will write and executive produce an untitled dramedy pilot for HBO, focusing on three adult sister who crave the affections of their mother, a literary lioness. The mother's love, though, goes mostly to their brother, who the trade describes as a "ne'er-do-well."
 
Sherman-Palladino successfully mined mother-daughter relationships for six seasons on The WB and The CW's "Gilmore Girls."
 
She had less success with the sisterly bonds on the short-lived FOX comedy "The Return of Jezebel James." That series was pushed to deep in the spring, had its episode order reduced, was pushed to an undesirable day (Fridays) and was eventually cancelled after only three airings, though the complete run is available on DVD.
 
This will be the first cable project for Sherman-Palladino, whose earlier TV credits include "Roseanne" and "Veronica's Closet."
