(Walk keeps telling her,“Don’t have to worry, Momma. Before I go bad I’ll let you know, send a Hallmark card ready-made for the occasion . ‘On the eve your son messes up.’”)But Walk is a good kid. So is his new friend, Matteo, though no one knows why Matteo will do absolutely anything that hot blond Brianna asks of him. Then Kirsten discovers something that shakes her and Walk to their cores. . . .
