OBLITERATE- The Ring of fire

It's the end. Obliteration.
It came out obvious with Martians starting to act like jerks, but what Destiny did not know was that she was involved in stopping it and causing it. Talk about double acting.
There were other things she did not know before she laid foot on the school with the rickety old gate.
She didn't know everything about her life was a big, fat lie. She didn't know her parents were criminals. She didn't know that her planet was crawling with tomato addicts.
At least one.
Most of all, she didn't know that she was going to be leaving the school because of a cannibal attack. Now, she and her sister have to set off 'into the goddamned wilderness' with the most annoying, charming blond upstart, a peppermint addicted Mars Man who's absolutely legit and a red-headed girl.
But things get way more worse when her sister gets kidnapped by the Martians.
With dozens of people dead and her own life in danger, will she possibly choose to take a risk with a problem involving her known family and two separate planets?
