Hell's Gate (Book 1 in new MULTIVERSE series) (English, Hardcover, Weber David)

by David Weber & Linda Evans The Union of Arcana has expanded through the portals linking parallel universes for over a century and a half. In that time, its soldiers and sorcerers have laid claim to one uninhabited planet after another. But all of that is about to come to a screeching halt, for the Union's scouts have just discovered a new portal, and on its far side lies a shattering revelation. Arcana is not alone, after all! There is another human society, Sharona, which has also been exploring the Multiverse, and as the initial disastrous contact snowballs into all-out warfare, both sides can agree on one thing. The portal which brought them together is Hell's Gate itself!
