Qualify (The Atlantis Grail Book 1) by Vera Nazarian

The Asteroid is coming… You have two options. You die or you Qualify… I am Gwen Lark. Nerd, klutz, loser, awkward smart girl. Somehow, I will save you all.

In 2047 an extinction level asteroid is hurtling toward Earth, and the descendants of ancient Atlantis have returned from the stars in their silver ships to offer humanity help. But they can only save a tiny percent of Earth’s teenage population. To be chosen, you must Qualify, or you die. Sixteen-year-old Gwen Lark is a klutzy nerd but determined to Qualify and rescue her entire family by competing in the brutal Games of the Atlantis Grail — against impossible odds and global competition — including sexy Logan Sangre. A high-octane dystopian SF teen adventure from a two-time Nebula Award Nominated author.
