Earth is under constant threat from Neighbors, invincible monsters from another dimension that destroy our way of life. At least we have the elite warriors of Border, who co-opt alien technology to fight back. Our hero Osami Mikumo may not be the best agent, but he'll do whatever it takes to defend life on Earth as we know it.

In the limbo that is Everlost, Mary, Nick, Allie, and others face the decisions that will determine whether that place and the Earth itself will continue to exist, as well as where their own futures lie.

"The Greek and Roman demigods will have to cooperate in order to defeat the giants released by the Earth Mother, Gaea. Then they will have to sail together to the ancient land--Greece itself--to find the Doors of Death"--Provided by publisher.
