The Fate of Ten

Penguin presents the audiobook edition of The Fate of Ten by Pittacus Lore, read by Neil Kaplan, Devon Sorvari, Almarie Guerra, Kyla Garcia.
For years the Garde have fought the Mogadorians in secret, but now the invasion has begun. If the Garde can't find a way to stop the Mogs, humanity will suffer the same fate as the Lorien: annihilation.
When the Elders sent the Garde to Earth, they had a plan - one which the Garde are finally starting to understand. A group of the Garde travelled to an ancient pyramid in Mexico where they awoke a power that had been hidden for generations. Now this power can save the world or destroy it. It will all depend on who wields it.
