Fatal Destiny by David DeLee

For bounty hunter Grace deHaviland, the job seemed simple. Track down Barry Keegan, a white collar defendant in a corporate embezzlement scandal who'd jumped bail. How hard could that be?
But the case turns deadly when Keegan's co-defendant ends up murdered, and Grace's best friend, sheriff's deputy Suzie Jensen, is nearly killed.
Drawn into a web of deception involving stolen mob money, old scores, and ruthless hit men, Grace must track down the elusive Keegan--a man who is far more dangerous than anyone could have guessed--while she tries to protect his wife and son from a past they though was long dead and buried.
