I actually think it's a little nicer than the first! When I read it I had to be in fourth or fifth grade- beginning of fifth at the latest.
So let's start off!
Sex: Nuh uh. Sure, more than last book, but literally it is JUST crushes, and one kiss. Alex has a lot of difficulty because he feels guilty for feeling a certain way about one girl when he'd always liked Lani- doesn't actually say they're dating, but they were more than friends. Samheed and Lani don't kiss, but they grow closer, since they were captured.
Language: Nonexistent basically
Violence: Eh. So yeah it's a violentish book, but it's advertised as being part Hunger Games. There are attacks on Artime that aren't really scary, the biggest thing would be the whole kidnapping Warbler does. Then Lani and Samheed are silenced with gold thorns being threaded THROUGH THEIR NECKS- but guess what?!? I loved that part Well not loved, but I distinctly remember thinking it was well a good book for it. And my review sounds worse than it does in the book. All it does is describe the screams of the people- and when they stop. Also, scabs and scars from them later being removed through a painless process. ALSO, Marcus Today is killed in this with FIVE heart attack spells, that Aaron throws. Over the top, right? But that's Aaron for you! Evil villain of the story SPOILER ALERT he becomes not evil later in the series, so don't worry bout that he is already having doubts.
And there are pretty good messages what with Alex getting through a really tough time, and Samheed and Lani too.
Thanks for reading this! Think that's all.
