(written from a Production point of view)
Star Trek: Deep Space Nine - Avatar is a two-part novel series, written by S.D. Perry. It forms the first installment of the "Relaunch" series, following events aboard the station after the final episode of Star Trek: Deep Space Nine, "What You Leave Behind". The two Avatar novels were later reprinted as part of the Twist of Faith omnibus.
When asked why the crew of the USS Enterprise were also featured in Avatar, Marco Palmieri commented: "It's fun. It's a bonus. It's relevant to the story, and it has echoes of "Emissary", which is fitting for what I think as a new beginning for DS9".
