Sparks Unlimited by Brenda Lowder

Sasha Timmerman’s purpose in life is not to find love for herself, but to help divorcing couples get back together—like she did for her mom and dad. Which is why she’s willing to don last-minute disguises and chase people down in frozen foods. By rekindling the sparks between couples experiencing a relationship hiccup, she enables them to continue their happily ever afters.
Contented bachelor Cole Chase is one of Atlanta’s top divorce attorneys. He scores the best settlements with the least amount of emotional fallout—until all his biggest cases start unraveling. Suddenly his promotion to partner isn’t looking like a done deal, and the mysterious Sasha Timmerman is at the center of every one of his cases-gone-wrong.
The world’s biggest action star hires Cole to handle his divorce, and the star’s wife secretly hires Sasha to reconcile them. When everyone gets stuck on the movie star’s private island, Sasha and Cole must fight their growing feelings for each other in order to battle on opposing sides in the bigger game of love.
