Hollow Places by Michelle Massaro

The mask she wears is the only identity she knows. But somehow he sees right through her.

Social worker Alli Johnson has built her identity around helping foster kids navigate the system she grew up in. But when one of her clients is placed at a religious group home, she’s forced to face the trauma that robbed her of her sense of self. And a too-hot pastor who sees past her defenses.
Delivered from years of pent-up rage, youth pastor David Porter wants to help others find the sense of peace God’s given him—especially the hurting seven-year-old and his spirited social worker. But he’s out of his depth with one, and dangerously attracted to the other.
As Alli and David’s mutual concern for the boy’s well-being draws them together, their differences—in background, perspective, and faith—tear them apart. They’ve both been shaped by terrible pasts. When pain devours a soul, it takes a limitless love to heal the hollow places left behind.
