Here's the blurb from the Abaddon Books website.
In case you haven't picked up Time's Arrow Part 1 - a.k.a. Red-Handed - it's not too late. You can do so here, and while you're pondering your purchase, here's a pleasing review of Part 1 too. (If you catch my meaning.)
It's tough to review this first instalment of the new Pax Britannia book fairly, since it is only the first third of the story. On top of that, not only do I, as a reader, not know where the story is going next, neither does the author: this instalment ends on a cliffhanger, and readers can go to the publisher's web site to vote on which way they think the story should go next. The second instalment will have a similar vote, and only after the third part is published as an ebook will the whole thing be released as a complete novel.
I can say, as someone who has only read the first Ulysses Quicksilver Pax Britannia novel before I read this one, it's fairly accessible. There's quite a bit of mention of earlier stories, but while I understood that I was coming in on the middle of a series, I didn't feel particularly lost. While this story very much seems to follow on from a cliffhanger in the previous book, I felt I had enough information to still enjoy it. Plus, once that cliffhanger was wrapped up, the new story was completely fresh and accessible.
What I ended up with was a fast-paced, science fiction, steampunk action-adventure, with some cute nods to genuine Victorian science fiction. The interactive part of the story was fun, and it's really got me looking forward to the next instalment (which is why I was willing to skip ahead in the series). And now I've got some time to get caught up!
