Cutting Loose by Tara Janzen (2007)

Janzen wrote all the books in the "Crazy" series and now she is working on the "Loose" series.
Zachary Prade, a CIA operative, is posing as a drug lord when a beautiful woman named Lilly Robbins seeks shelter from the rain at his plantation. He learns that Lily, a schoolteacher, holds the key to a valuable encoded file and it is about to fall into the wrong hands. He has to get it from her even if it means blowing his cover. Lily never dreamed she meet up again with Alejandro (Zachary) after he saved her life when she got caught in the middle of a nasty drug-guerilla war. Even though she knows he is one of the "bad guys," she can't help feel some really hot passion for him that is absolutely criminal! Now together again, they will have to see if they can live long enough to enjoy it.
Tara Janzen writes some very sexy stuff along with a great plot that will keep you on the edge of your seat. Each "Loose" book has different characters so you can enjoy some high octane fun!
