Deceptive Desires (Second Sisters #1)
Lilly LaRue

Aronne has to stay in the marriage for two years, or he'll be disowned. Before the ink dries on the marriage license, he's on a plane to Rio, with no plans to return until they can divorce. He ignores all communication attempts from Molly, until she stops trying.
Two years later, they're reunited earlier than expected when his mother has a heart attack. She wants them to reconcile. That isn't the only shock in store for the errant bridegroom...and daddy.
