The Steam Pump Jump

  The great thing about this series is that it is not too difficult to dip in and out of the supplementary novellas when the fancy takes you, as the narrative is forever jumping around in time anyway, although it's probably best you don't read the ones set in between main books you've not read yet, in case of casually dropped spoilers or general confusion. 

This particular novella was The Steam Pump Jump, which is set between novels 9 and 10. The St. Mary's series is, in my opinion, excellent however you consume it, but it is one of those series that is truly magnificently narrated on audiobook. Zara Ramm has narrated all of the books and novellas, and I believe also the spin off series the Time Police, and she is just so good. Know if I read any St Mary's I automatically hear her voices for all the characters and I wouldn't want it any other way. This novella, like it's brethren in the rest of the St Mary series, was warm and amusing. I especially loved this one as it has a lot of my favourite character in the series, Markham. This got a 5/5 from me, which to be honest most If not all St Mary's books do, as usually my only complaint is that they have to eventually end, and I could just live in this world forever.
