His Special Angel by Lynne Marshall

One off-limits doc…one very special nurse
Mercy Inc.’s favorite nurse, Mallory Glenn, has always admired her boss from afar. As a working single mom, personal responsibility takes precedence over silly crushes, and the newly divorced doctor is strictly off-limits. Then tragedy strikes, and Mallory knows she must step in and care for the man who has always touched her heart.
J.T. Prescott is used to being active, strong and in control, so he doesn’t make the best patient. But he can’t deny the healing skills and tender touch of the annoyingly upbeat nurse, Mallory. Nor can he resist the temptation of this very special angel.
