Just beyond the clouds : a novel / Karen Kingsbury.

Enhanced descriptions from Syndetics:

#1 bestselling author Karen Kingsbury tells the heartwrenching story of Cody Gunner, a widower fighting for stability, and the woman who wants to help him trust again -- even when trust is the most terrifying thing of all.

Still aching over his wife's death, Cody Gunner can't bear the thought of also letting go of his Down's Syndrome brother, Carl Joseph. Cody wants his brother home, where he will be safe and cared for, not out on his own in a world that Cody knows all too well can be heartless and insecure. So when Carl Joseph's teacher, Elle, begins championing his independence, she finds herself at odds with Cody. But even as these two battle it out, they can't deny the instinctive connection they share, and Cody faces a crisis of the heart. What if Elle is the one woman who can teach Cody that love is still possible? If Cody can let go of his lingering anger, he might just see that sometimes the brightest hope of all lies just beyond the clouds.
