A third box set, Legion, is due for release in September and features three new adventures. Vesuvius Falling, written by Tony Lee, sees Bernice and her friends investigating a millennia-old murder aboard a spaceship on a collision course with their new home. It guest stars Kai Owen (Torchwood), Andrew Hayden-Smith (Doctor Who's Jake Simmonds, Byker Grove) and Jennie Stoller.

The second instalment - Shades of Gray, written by Scott Handcock - finds Bernice and her friends forced to relive a trilogy of horror stories inside an old, dilapidated house on the dark side of Legion. A house where a valuable artefact is believed to have been hidden... Alexander Vlahos (The Indian Doctor, Doctor Who: The Gunpowder Plot) and Richard Franklin (Doctor Who's Captain Mike Yates) guest star.

The third and final adventure - Everybody Loves Irving - is written by Braxiatel's alter ego Miles Richardson, and sees Bernice's old acquaintance trying to rebuild her trust in him by means of an ill-fated shopping trip. Guest stars include Cameron Blakely, Matt Butcher and Andrew Macklin.

2013 will then see Bernice's adventures continue in two brand new box sets: a three-CD set entitled New Frontiers in April, followed by a bumper five-CD set - Missing Persons - later in the year.

Legion, New Frontiers and Missing Persons are now available to pre-order on CD and download. Many Happy Returns is also available to pre-order as a download only.
