Hell Hath No Fury (Book 2 in New Multiverse Series), 2

It began with two men. They came from very different worlds--entirely different universes, in fact--one using sorcery and the other using mental powers and steam-age technology. They met in a virgin forest on a duplicate planet Earth. Neither side knows who shot first, but each blames the other, and it doesn't really matter, now, because war has begun. War between the universes is the last thing responsible leaders on either side want. But the fury of their respective populations, xenophobic fear of the unknown, and cries for justice (or vengeance), are all driving both sides towards the brink. And unscrupulous, power-hungry men--and Arcana and Sharona alike--have agendas of their own. The fuse has been lit, and a war stretching across the universes, fought between dragons, spells, and crossbows and repeating rifles, machine guns, and artillery is erupting in white-hot rage and fury. Where it will end--and how--no one knows
