"Megan Flynn thought she was falling in love. Cole Williams wasn't just handsome and passionate, he was one of the good guys. Or so she thought, until he arrested her brother--the only family she has left--for a murder she knows he couldn't have possibly committed. Now, with her heart broken and her brother's life hanging in the balance, Megan will risk everything to prove his innocence.
