An Un-Calibrated Centrifuge

This series is really up and down for me. One of the main plot points in this one is so unbelievable. Also there's a lack of consistency between the books. Ledward was originally half Hawaiian, half a bunch of other things. Now he's half Hawaiian, half Filipino. Clarence was described as Samoan the first time we meet him, but in this book he's described as Hawaiian (not everyone who lives in Hawai'i is Hawaiian... it's an actual ethnicity).

And Stella's race is never mentioned. Earlier in the series it seemed like Salisbury would be good about describing race (eg when Willy first comes it's noted that he's the only haole on the street and the only blond kid in class), but the longer the series goes on the more and more non-white characters are described and white characters aren't (which reads: white is the default).

There's also a bit where Calvin explains flooding which why? I'm pretty sure most people (even kids) know what flooding is even if they've never seen it.

So far this is my least favorite book of the series. I definitely hope the next book is better.
