When two law enforcers reunite to protect a key witness, the only thing more dangerous than the cartel is the chemistry between them...

Deputy US marshal Nova Bennett and DEA special agent River Randolph have one mission: safeguard a former money launderer from the Mancuso cartel. But when the witness is killed and his wife flees witness protection, Nova and River embark on a cross-country search to keep the terrified target alive. With the murderers hot on their trail and the rising danger only rivaled by their attraction, these two seasoned pros will risk everything to locate the innocent victim and bring her back alive.
