Desert Wolf by Marianne Hull

He came to betray…
Wolf shifter Ziri Talhaoui’s clan chief has ordered him to defect to Clan Baumann as a spy. He’s not terribly happy, but honor demands that he obey. Problems arise on the first day when he finds his true mate at Clan Baumann headquarters. Who will he give his loyalty to now? Shifters kill traitors. How can he serve two clans and stay alive?
Cat shifter Connie Capone feels robbed when her true mate turns out to be someone her own clan doesn’t trust. At first she balks when her clan chief asks her to report Ziri’s activities, but as she senses his lies through their mating bond, she agrees. And when his ultimate lie is discovered, will she choose the mate she’s grown to love, or the clan that’s been her family for hundreds of years?
