The Family Chao by Lan Samantha Chang

For years, the residents of Lake Haven, Wisconsin ignored the whispered troubles about the Chao family, if only to keep eating at the best restaurant in town.

But when tyrannical patriarch Big Chao is found frozen to death in the family's meat freezer, scandalous events force the community to turn its attention to the three Chao sons.
Dagou - presupposed heir to the business.
Ming - accomplished city lawyer, determined to sever ties with Haven's Asian community once and for all.
James - naive college student, who is only just learning of his family's past.
When the family's dog mysteriously disappears, and Dagou 'Dog Eater' Chao is held on trial for his father's murder, the Chaos' turbulent history spills into the public eye, while a small town looks on in disbelief. . .
