Stranger at the Door

What if love isn't what it seems to be? 

For Isabel and Sam Lambert it was love at first sight. And since then, they've created a good life together. But when a stranger named Mark Taylor knocks on their door, claiming to be Sam's son, Isabel is shocked to realize that her life might be nothing but lies. 

Isabel wants answers from Sam, but he's retreated, leaving her to sort through everything they've shared and decide what kind of future they have. Reconciling themselves to the past is one thing; moving on in the present is another. Can she trust him—and her love—enough to rebuild their relationship?
