Deluge (Paperback) (ISBN-13: 9781071304907)

Major Tor Savan has built his career on one fundamental principle - protect planet Earth, whatever the personal cost. To a certain degree, he's succeeded, warning Earth about a deadly missile strike from Mars and then being injured as his own ship fought in the battle.

But as the dust settles after the attack, Tor learns that a new crisis is threatening the planet. As a result of the missile strike, the laboratories that manufacture omegas' hormonal suppressants have been destroyed, which means that every single omega on Earth will soon be forced to go through a heat.

Tor is unwilling to abandon his fellow soldiers to twelve hours of agony. But fortunately, he has a level of knowledge about the heats that few alphas could match. With the powers-that-be turning their backs on omegas, Tor puts together a plan to help them through their heats - a plan so risky and unlawful it could not only end his career, but also destroy the reputations of every single person involved.

But only a fool expects such daring plans to go smoothly, and when Azure, Tor's omega lover, gets dragged into the middle of the storm, Tor finds himself having to re-evaluate every social custom and moral value he believes in.

Tor and Azure's story began in Hurricane and continues in Lava. Books are best read in order.
