Hour of Need by Melinda Leigh

While fighting in Afghanistan, Major Grant Barrett receives devastating news: his brother and sister-in-law have been murdered in Scarlet Falls, the sleepy suburb of Grant’s youth. Emotionally scarred from war, the career soldier returns home on emergency leave to temporarily care for his orphaned nephew and niece. But when someone tries to kidnap the kids and their teenage babysitter, Grant knows it’s not a random act…and neither were the murders.

Already devastated by her neighbors’ violent deaths, Ellie Ross is shattered by the attempted abduction of her teenage daughter so she desperately turns to Grant for help. As they navigate a deadly search for the truth, they struggle with growing feelings for each other and Grant’s impending return to deployment.

But time is running out. The killer is growing bolder by the hour, and Ellie and Grant must find him before the children become his next victims.
