Equinox Zero is a nice filler novel, one where there really isn't anything as drastic as we had with The Dragon Kings and previous novels.
Sure the novel revolves around another world-threatening event, but it's resolved quickly and quite memorably at the end.
We need the occasional -breather- novel as we have had with this one. There is plenty of action, to be sure, but at the same time, there is even more character development, which compliments the action quite beautifully.
The novel begins with Kane and Domi hunting for a prehistoric monster on Thunder Isle, to make the violent and primordial island just a little bit safer for the Cerberus exiles, while they explore the ruins of the Operation Chronos facility.
The author gives even more depth to the outlander girl, Domi, and adds a little tension between her and Kane, as she makes it quite clear that she is interested in him, despite the relationship that has blossomed between her and Lakesh, after Grant rejected her.
Speaking of the ebony giant, he has decided to leave Cerberus, as he is tired of all the fighting and the near endless stress that he's been subjected to. He really doesn't believe that it's his fight, and he just wants to retire, to settle down with Shizuka and the Tigers of Heaven on new Edo.
Another old enemy has apparently arisen from the grave, a man we haven't seen since Iceblood. He managed to find his way to Utlima Thule, a haven of Vikings that has remained essentially untouched for thousands of years. Using his influence, he is trying to take over the isolated civilization, and to bring about another great Deluge, not quite of biblical proportions, but one that would destroy the emerging civilization, plunging the already fragile planet back into another dark age, of which it might not ever recover.
Zakat and a ship of the people from Ultima Thule raid a ship belonging to the Tigers of Heaven, all the while being witnessed by Grant and his new love. That prompts him to return to Cerberus to ask for Kane's help in tracking down the criminal and putting an end to him and his plans once and for all.
Bringing Philboyd with them, they jump to the gateway that was first discovered in Hell Rising. They find the entrance to Ultima Thule and make their way to the underground city. It is very much a lost civilization, even though the Nazi's tried to take it over nearly 250 years previously. Tried, but failed miserably, and paid for their efforts with their lives.
Here, Kane is forced to fight Zakat's lover, a Valkyrie named Sif. It is truly a memorable battle, one which Kane nearly loses his life, but as is the case, the hero triumphs, and not only defeats the woman, but spares her life. Zakat meets his end in a very appropriate manner, and the threat to the world is neatly dealt with.
Keep them coming!
