Love Is for the Birds by Diane Owens Prettyman

The Texas Gulf: beautiful yet unpredictable.
A beach town destroyed. Her mother’s candy store swept away. This is what Teddy Wainsworth faces when she returns to Bird Isle. Meanwhile, Jack Shaughness, owner of a popular barbecue restaurant chain and widower still grieving the death of his wife, receives permission to cross over to the island with a smoker full of brisket to feed hurricane survivors. Soon after arriving, he meets Teddy and immediately finds himself drawn to her—which makes him feel he is betraying his wife. When the two find a lost dog, Jack convinces Teddy to take it home while they attempt to find the owner, creating a bond that brings them closer.
In the wake of the hurricane, Bird Isle residents fear the Aransas Wildlife Refuge will not be ready for the whooping cranes’ annual migration south. Seeing that Jack has important connections and a love for the island, they enlist him to help restore the habitat of the endangered cranes before they fly to Padre Island for the winter. With their rescued dog always nearby, Teddy and Jack work side by side to rebuild Bird Isle for the return of the whooping cranes. But Jack is harboring a secret that may ruin everything he and Teddy are creating—and he won’t be able to keep that secret forever.
