It marked the first release of Doctor Who prose fiction by Big Finish, which previously had only produced audio dramas based upon the series.

Publisher's summary Edit
Take a TARDIS trip through the constellations, as the Doctor travels to twelve thrilling tales inspired by the mystical zodiac.
Telepathic fish, miniature lions and twin planets are the least of his problems, as the Doctor — all eight of him — faces the Capricorn Killer, endures a mindswap with the Machiavellian Master, and dances with Death herself.
And that's not the half of it — as the two K9s can attest.
This collection features twelve exclusive short stories from well-known names in Doctor Who fiction — including acclaimed novelist and Booker nominee Paul Magrs, alongside Simon A. Forward, Mark Michalowski, Paul Leonard and Joseph Lidster — as well as fresh new voices.
