I can sum this book up in a handful of words: 
 Arrive at location X. Infodump. Facenoms. Infodump. Facenoms. Tension between characters. Infodump. MASSIVE PLOT HOLE! Infodump. Infodump. Facenoms. PLOT BEGINS. Drivel. Drivel. Drivel. "Controversial ending". 
 I've reviewed the series on my blog. Check it out here - it is spoiler-free!
