''SECOND TIME AROUND'' by KATHERINE ALLRED

Five years ago Quinn McAllister's life was almost destroyed. While he lay in a coma from injuries sustained during an auto accident, the woman he loved divorced him. Or so his father told him. Now he's discovered that his divorce was bogus, and his whole world is spinning out of control. He's tempted to give his wife the quick divorce she wants until he finds out about the son he didn't know existed. Now he's going back to Wyoming to claim what's his, and nothing can stop him...not his father, and certainly not his wife's fiance. It's taken Lanie McAllister five years to get over losing the man she loved with every fiber of her being. Now she's ready to move on with her life, and has even agreed to marry the local veterinarian until Quinn gives her an ultimatum. Give them three months to try to mend the marriage his father tore apart, or he'll fight her tooth and nail for custody of their son. Torn between the man her heart has never quite forgotten and the man she's engaged to, Lanie can only pray that love will truly be better the second time around.
