4.5 rounded up.
Although I've read several of the New Who Adventure novels, this is the first work by Big Finish Productions that I've ever read and I'm hooked! These take audiodrama to a whole new level - the story and sound are so immersive and just throw you right into the thick of things. And the stories (while not like, Russell T. Davies level of storytelling) are fun and feel true to the Whoniverse. I'm really enjoying this particular arc that fills in some of the gaps in Rose's timeline after the events of "Doomsday" and before "Turn Left"/"The Stolen Earth". It helps flesh out relationships and even problems that we may have encountered in the show (like Rose being so chummy with Pete-who-isn't-her-Pete) while giving fresh adventures and giving us the chance to see Rose grow without the Doctor being by her side.
Although I'm a sucker for a happy ending, I was appreciative of the fact that "The Dimension Cannon" didn't try to force feed readers a neatly tied-up pleasant story, and instead took the chance to focus on other what-if style worlds that prompted reflection and some heavier themes. I can already tell that this is definitely a series where all three books will have to be read to get a conclusion, but I'm totally looking forwards to that process! ( )

I really enjoyed this first series with Rose and cannot wait til the next installment is released. ( )
