I anticipated this book SO much when I first heard about it, but now I'm just disappointed. 
 I really love the concept of being able to travel to any time or place with a detailed and dated map. That sounds amazing! What I didn't love was how confusing it got with the different time jumps and references to different time periods. I skim-read chunks hoping I would be able to figure things out as it was wrapping up, and I kind of did... Kind of. Luckily, it read pretty quickly so it didn't take up too much of my time. 
 As for the characters: Nix is okay but really needs to speak up more; Kashmir is hands-down my favourite with his charm, wit, and banter; Slate is a dick and I was over him from the very beginning; and I didn't need Blake in the story at all. Lots of multiculturalism amongst the crew which was fantastic! 
 Really wished I loved this more. Looks like it's only a duology so I'll still check out the sequel.
