Maybe my last.They made their presence on Earth known thirteen years ago.Providing technology and scientific insights far beyond what mankind was capable of. They became indispensable advisors and promised even more gifts that we just couldn't pass up. We called them Gurus.It took them a while to drop the other shoe. You can see why, looking back.It was a very big shoe, completely slathered in crap.They had been hounded by mortal enemies from sun to sun, planet to planet, and were now stretched thin -- and they needed our help.And so our first bill came due. Skyrines like me were volunteered to pay the price. As always.These enemies were already inside our solar system and were moving to establish a beachhead, but not on Earth.On Mars.

    . . . The impossible has spawned the unthinkable. A military experiment in the year 2021 has thrust an American-led multinational armada back to 1942, right into the middle of the U.S. naval task force speeding toward Midway Atoll—and what was to be the most spectacular U.S. triumph of the entire war. Thousands died in the chaos, but the ripples had only begun. For these veterans of Pearl Harbor—led by Admirals Nimitz, Halsey, and Spruance—have never seen a helicopter, or a satellite link, or a nuclear weapon. And they’ve never encountered an African American colonel or a British naval commander who was a woman and half-Pakistani. While they embrace the armada’s awesome firepower, they may find the twenty-first century sailors themselves far from acceptable.Initial jubilation at news the Allies would win the war is quickly doused by the chilling realization that the time travelers themselves—by their very presence—have rendered history null and void. Celebration turns to dread when the possibility arises that other elements of the twenty-first century task force may have also made the trip—and might now be aiding Yamamoto and the Japanese.What happens next is anybody’s guess—and everybody’s nightmare. . . .From the Trade Paperback edition.

    GANNON AND ROBERT WATERSDomingos Fernandes Calabar started out as a military advisor for the Portuguese in Brazil. But to his superiors, he was still nothing more than a mameluco, a man of mixed blood. Until, that is, the Dutch arrived and he switched sides. Then the Portuguese had a new label for him: “traitorous dog.” But when Dutch admiral Maarten Tromp arrives, having barely survived the disastrous Battle of Dunkirk, Calabar’s job changes again. Now he has to help engineer a swift Dutch exodus to a safer place before word of Tromp’s defeat reaches Spanish ears. Partnered with the Sephardic pirate Moses Cohen Henriques, the two aid the battered Dutch fleet by striking at the Portuguese and Spanish, both on land and sea. Until, that is, Calabar learns that bitter personal enemies have grabbed his family, put them in chains, and sold them to a slaveship bound for the Spanish Main. Calabar must now choose: continue to help the Dutch, or save his wife and children? Tromp and other strong allies want to put an end to slavery, too, but their strategies and timetable are measured in months and years. Calabar doesn’t have that kind of time and can’t rely on their methods. The struggle to recover his family, and to free the millions more suffering in shackles, is one he must win in his own way and on his own terms. Because ultimately, this is not just  Calabar’s fight. This is Calabar’s war.

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 the first contact between them did not go well.

Both sides think the other fired first, and no one on either side understands the "technology" of the other. But 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!
