She was off limits until her life was on the line...

Agent Shane Baker has denied his attraction to his best friend's younger sister for years. But when computer guru Makena Kingston's latest online investigation stirs up a series of break-ins, Shane isn't about to let the vulnerable beauty fend for herself.

Makena refuses to be seen as anything but the alpha male's equal...even as she finds comfort in his protective arms. But soon they uncover the threat to Makena is closer than either of them expected. With Shane's bodyguard instincts on overdrive, he knows keeping his professional distance will be nearly impossible. Because even the most highly trained operative has his breaking point.
