I became a fan of Ms. Sala's writing after reading the 1st book in her Forces of Nature trilogy, Going Once, and I was equally impressed with this 2nd addition, Going Twice. Wade Luckett and his ex-wife Jo Luckett, both FBI agents, are assigned to the same case and the serial killer they are tracking, targets Jo. The backstory given for the reason behind the breakup of their marriage, adds a poignant aspect to this action packed romantic suspense story. I heartily recommend books 1 and 2 of this thrilling trio and I'm looking forward to reading book 3, Going Gone.
