The Bradshaw brothers never dreamed they'd return to their hometown. But tragedy has brought them back together in Benevolence, Washington, where they're finding generosity, surprising revelations'and unexpected love . . .   Sullivan Bradshaw is in way over his head. A car crash killed his brother, Matthias, and critically injured his sister-in-law. It's Sullivan's turn to care for the couple's six children and the ancestral farm, but the die-hard bachelor and art professor is hardly family-man material. What he needs is the perfect nanny-miracle worker-saint. What he gets is pretty Rumer Truehart, a free spirit who will change everything he ever thought he wanted . . .   Rumer learned the hard way that nothing is for sure, much less forever. And she certainly  understands why Sullivan's unhappy childhood makes him a strictly no-commitments kind of guy. But she can't help being drawn to this thoughtful, gentle man. And when trouble strikes, she's determined to win his trust'and show him love can be a promise for keeps.   Praise for Shirlee McCoy's Sweet Haven   'Fans of Debbie Macomber will appreciate McCoy's sweet, funny, heartwarming romance with its friendly, small-town setting.'  --Booklist (starred review)    'A delicious small'town treat.'
