Librarian's note: This ISBN was previously used on another book. Her heart's gone AWOL! Ever since Lieutenant Colonel Ryder McGrath broke Major Hope Evan's heart, she's devoted her life to the military. But now a strange mission has thrown Hope and Ryder together again. Something odd is going on at a dismantled-missile site in Arizona. Is the problem a mere figment of Hope's father's imagination or is it something more sinister? Hope and Ryder seem to be the only ones who are worried about it as they race against time and the enemy to prove their suspicions correct. Once again, Ryder and Hope find they're an unbeatable team - and they rekindle the love that never truly died. But is it too late to save what might have been?
