Kiss of Eon by Anna Hackett

When the vital alliance between Earth and the Eon Empire depends on her playing war games with an arrogant, infuriating Eon warrior, what could go wrong?

Terran Captain Allie Borden has her orders. Take her ship, the Divergent, and strengthen the alliance with the Eon by carrying out training exercises with the Eon warship, the Desteron. The only problem…one annoying warrior who gets on her nerves like nobody else. Forced to work with Second Commander Brack Thann-Felis, Allie finds her diplomacy skills stretched to the limit…and her body betraying her with a white-hot desire that’s getting hard to ignore.
Brack Thann-Felis is dedicated to his ship, his warriors, and his job. Watching his parents’ disastrous marriage has ensured that he will never mate or fall in love. Working with feisty, opinionated Allie tests his patience, but the more time he spends with the dedicated captain, the more he finds he can’t stay away from her.
As mysterious, dangerous sabotage events strike their ships, it becomes evident that someone wants their alliance to fail. They might have traitors among their crew and they both know it has to lead back to their enemy—the ravenous insectoid Kantos. Soon, Brack and Allie find themselves in a fight for their lives, with only each other to depend on, and a growing desire that will not be denied.
