Nope, I just have the first 4, buying them in order.
Hmmmm...Wkik'ing it, I see A Death in the Family is with Ace and Seven, where'd that come from? (Don't tell me if it's really spoilery)
Looks like I'll have to buy that one, and hang onto it until I get there
I've just listened to the first Evelyn story, I like her, she is an excellent foil for the Doctor.
I think my next Big Finish stories will be more of her adventures.
