The Best Man's Bride by Anne McAllister

Rock star Jack Masterson is every woman's fantasy. His sex appeal, charm, and killer looks make women everywhere fall at his feet...except for Celina Harris, the one who got away. It's taken two years for Celina to put her life—and heart—back together. Now the personal assistant to San Michele's Serene Dowager Margaret, Celine has things under control. She spends her days assuaging royal egos and her nights in peaceful solitude. The last thing she needs is a reunion with Jack. When they are thrown together, Celina is determined to resist Jack's charm. But Jack doesn't give up easily and seeing Celina awakens all his former desire. Can Celina resist the former love of her life, or will he break her heart all over again?
