The Noblest Vengeance - Have Body, Will Guard, #6

An only child, Aidan has deep family feelings for his cousins. When one of them needs his help, he steps up, even if the case could be deadly. Bodyguard partners Aidan and Liam are deeply in love, living as expatriates in Nice, France. Aidan's cousin, of Sephardic Jewish heritage, calls to enlist their help in protecting members of her family who still live in Istanbul. They are rushing to leave the country when threats against them erupt.
Can Aidan and Liam protect them until their exit visas are approved? Aidan is thrilled to learn about his Sephardic connections, until an accident occurs that reminds him and Liam that the threat is real. But the real danger to their relationship may come from their very different ideas about family connections. Can their love withstand assassins with a deadly secret to keep hidden - and Liam's foul-mouthed mother?
