Book review: Under the never sky by Veronica Rossi

Summary: WORLDS KEPT THEM APART. DESTINY BROUGHT THEM TOGETHER.
Aria has lived her whole life in the protected dome of Reverie. Her entire world confined to its spaces, she's never thought to dream of what lies beyond its doors. So when her mother goes missing, Aria knows her chances of surviving in the outer wasteland long enough to find her are slim.
Then Aria meets an outsider named Perry. He's searching for someone too. He's also wild - a savage - but might be her best hope at staying alive.
If they can survive, they are each other's best hope for finding answers.

Review: Yet another great new book! The story is set in the future or an alternate world (this isn't made clear by the author telling us a history lesson, which works perfectly). 'Dwellers' live in gigantic domes to protect themselves from the fumes and poisonous gases, and 'Outsiders' (or 'Savages') live in the wilderness beyond the main settlement. Aria's mother is a scientist for the Dwellers, and when her mother goes missing Aria becomes hell-bent on finding out the truth. The Dwellers are run by a totalitarian government (although they don't seem it) who insist that nothing is wrong and that it was all an accident; but a recorded message from Aria's mother tells her otherwise.
Within the Outsiders are groups  of people who have gifts (all this is unknown to the Dwellers). There are: Audibles, who can hear over great distances; Seers, some of whom can see far in the day, others at night; and Scires who can smell people's emotions (which sounds really weird when you put it that way).
Peregrine (or Perry) is the Outsider who helps Aria, another main protagonist. The story is told alternating between the two, which I find always helps a story as you see everyone's perspective on the tale. Perry wants Aria's help to  retrieve his nephew from the Dwellers, who stole Talon when they were out hunting.
Aria is an interesting character, as when she is 'on the outside' she starts developing in new ways. Aria's mother was a geneticist, and told Aria that she had been engineered (for lack of a better word) her to be a phenomenal singer, a falcon soprano. Aria enlists Perry to help her rescue her mother from the damaged dome where she went missing.
The whole world of Under the Never Sky is intriguing - full of marked (gifted) people, old-age traditions such as marrying your sister for the good of the tribe, and much more.
So, another great book which pushes the boundaries of teen fiction and shows a fuller imagination beyond what we would expect. The ending is cleverly mastered so that it could become part of a series, or be left as a stand-alone title. Overall, 4.4 stars (on reflection).
