Between Burning Worlds: System Divine, Book 2

Parents need to know that Between Burning Worlds is the second volume of the sci-fi System Divine series begun with Sky Without Stars and loosely patterned after Victor Hugo's Les Misérables. At a hefty 688 pages, it's best for strongly independent and highly motivated readers. There's a list of characters at the beginning to refresh your memory or get you up to speed if you didn't read the first volume, but appreciation of the world and the characters will be much deeper if you read them in order. Violence is mostly fights and riots with mention of blood, injuries, pain, and sounds of violence but no gore. There's one horrific description of a cage-style fight between to men to the death. Large-scale destruction like factory explosions causes death and injury, and characters are frequently in intense danger of being captured or killed in crashing space ships, etc. Sexy stuff is light, with some romantic feelings, a past remembered kiss, and a same-sex couple seen kissing at their wedding. There's also very little language of concern, except the term "blood whores" to describe young women who sell their blood. Overall messages are positive about teens learning to work through their sense of betrayal, what battles are worth fighting, and how to work together to change the system they're living in.
