The Yuletide Angel - Barnes Brothers, #1

Who is the mysterious Yuletide Angel? In the weeks leading up to Christmas, Violet Madison ventures out at night to leave packages at the houses of the poor. When her brother announces his upcoming marriage, Violet realizes she'll soon lose her role as mistress of her childhood home. Worse, without a way to support herself, she could lose the roof over her head and become as needy as those she helps. A betrayal by his brother and a past love turned Hugh Barnes into a confirmed bachelor.
Now drawn to Violet, Hugh discovers that his sweet, shy neighbor is the anonymous and charitable Yuletide Angel. As much as he admires her spirit, he's horrified by the risk she takes in traveling alone during the wee hours and vows to protect her. Hugh's discovery of Violet in the company of his reprobate brother endangers their growing romance. However, the biggest threat to their love might come from the one hiding in the late-night shadows.
