The Gathering: The Second Draeken War #2 (The Chronicles of Lumineia)

Born of darkness, the ultimate army has been unleashed. The only hope lies in destroying the source—before all life is extinguished. Fate has chosen Elseerian for the impossible feat, but as he embarks on the harrowing journey the invasion must be delayed. With time as their only weapon against extinction, the elves issue a desperate call . . . for every race to ally. Facing annihilation, many will realize that survival lies in unity, courage sleeps in ordinary citizens, and average people can turn the tide of war.

The Gathering has begun.
