In the key of love 

Joi Lewis's security firm is vying for a lucrative contract with an international bank. But there's a glitch she never could have predicted: Marco Alvarez. Years ago, Joi left Marco's friend at the altar. Now she must prove her trustworthiness to the gorgeous, albeit guarded, man standing between her and success. Soon business meetings give way to jazz-filled evenings that hold the promise of deep, mutual satisfaction. 

Can Marco rely on Joi to protect his bank when she hasn't always followed through on promises in the past? His first instinct is to say no. Yet this isn't the same naive young woman he knew before. She's confident and alluring, daring him to open up in ways he never has. But a safety breach and a past secret could destroy everything, unless they're willing to fight to keep their passionate duet alive.
