Audrey Moretti always knew she wanted to be a police officer, but she never expected it would take her on the most harrowing venture of her life-the search for her sister on September 11th, 2001... Audrey has made it to the final weeks of the police academy, and after five grueling months, she's solely focused on graduating. But on a quiet Tuesday morning, her life changes in an instant when she hears that an airplane has struck the World Trade Center. She knows her sister, Hannah, is in trouble; she can feel it. In a bold move, she risks all and finds herself at Ground Zero-a decision that will change her world forever. Hannah, a young Wall Street hopeful, works on the 84th floor in the South Tower of the World Trade Center. In the weeks leading up to the attacks of 9/11, everything is going right. Her career is taking off, and she unexpectedly finds true love in the city. When she witnesses from her office window the first plane strike the North Tower, nothing will ever be the same again. She follows her instinct to evacuate the South Tower, but will she escape the stairwell before the tower collapses...? Haunting questions remain for years after the tragedy, until a visit from a stranger and a handwritten note surface. Grief makes way for hope, in this deeply moving story of love, loss, strength, and courage, during a dark time in America's recent history. BLUE SKY GONE will take the reader on an emotional and powerful journey before, during, and after September 11th, 2001.
