Our host for this month is Sharon Grimshaw.

Our book is "Two Nights in Lisbon: A Novel," by Chris Pavone.

Ariel Pryce wakes up in Lisbon, alone. Her husband is gone with no warning, no note, not answering his phone. She starts with hotel security, then the police, then the American embassy, at each confronting questions she can’t fully answer: What exactly is John doing in Lisbon? Why would he drag her along on his business trip? Who would want to harm him? And why does she know so little about her new—much younger—husband? Tautly wound and expertly crafted, this is a riveting thriller about a woman under pressure, and how far she will go when everything is on the line.
