Here's the story synopsis from Goodreads:
In a desperate attempt
to escape destruction decades earlier, humankind was forced underground,
into the depths of the earth, creating a new society called the
Tri-Realms. After her parents and sister are abducted by the
Enforcers, seventeen-year-old Adele, a member of the middle-class moon
dwellers, is unjustly sentenced to life in prison for her parents'
crimes of treason.Against all odds, Adele must escape from the
Pen and find her family, while being hunted by a deranged, killing
machine named Rivet, who works for the President. She is helped by two
other inmates, Tawni and Cole, each of whom have dark secrets that are
better left undiscovered. Other than her friends, the only thing she has
going for her is a wicked roundhouse kick and two fists that have been
well-trained for combat by her father.
At the other end of the
social spectrum is Tristan, the son of the President and a sun dweller.
His mother is gone. He hates his father. Backed by only his servant and
best friend, Roc, he leaves his lavish lifestyle in the Sun Realm,
seeking to make something good out of his troubled life.
war breaks out within the Tri-Realms, Tristan is thrust into the middle
of a conflict that seems to mysteriously follow Adele as she seeks to
find her family and uncover her parents true past.
This is one of those YA reads I didn't really know how to rate. There were parts that were fully deserving of five stars, but at the same time (for me anyway), there were parts that pulled it back. I loved the whole idea and the setting - the author has done a splendid job of creating an underground world complete with an evil oppressive government and imagination teasing labels (the Sun Realm, the Moon Realm and the Star Realm). It made for a fantastically dystopian world, perfect for a budding/struggling revolution and challenge-laden characters. Plus, the adventure the characters were thrown into was page turner enough to keep me interested (although it was slower to progress than I expected). Even the action sequences were great, very well described (although maybe fewer roundhouse kicks would be better). So for many YAers I can see this being five stars. However, for me there was one thing I couldn't quite get past, and that was how the story swung between Adele's and Tristan's viewpoints. Although it works sometimes, I found that the overall result was to slow the story down by going over a scene from a different perspective (and sometimes providing too much character thinking time).
Again, just because the writing perspective didn't work for me doesn't mean it won't work for others. The story had all those other things that make it appealing: danger, star-crossed lovers (although they don't know it yet), heroic good looking young people and evil bad guys. So I have to say, it's well worth a try.
