Each of the Invisible Library books seem to take on a different genre and this one was like a heist movie. The librarian and her dragon companion had to team up with a band of criminals to steal from a big bad guy. They all had their own motivations which aligned enough for them to work together for a while but the trick was to know who to trust, and how much, and for how long.. It was quite exciting and if you like that kind of thing then you would enjoy it, I guess. I’m not a fan of heist movies, and I’m getting a bit bored of the whole Invisible Library series if I’m honest. I think I have at least one more in my Kindle library, so I’ll read it some time, but I’m not in any great hurry to look at the next installment.
