The next Man on a Mission hero safeguards his charge until she reaches the witness stand — and his heart.

Caterina 'Cate' Mateja is prepping her testimony against the crime kingpin who enslaved her when his henchmen open fire in the courthouse, narrowly missing her. US Diplomatic Security Service agent Liam Jones dodges bullets to get her to safety, and yet the gorgeous man seems to want nothing to do with Cate's case — or her.

It's not Liam's job to protect Cate. But after he discovers everything she's been through, he makes it his personal mission to ensure she'll have her day on the witness stand. Staying by her side 24-7 may mean opening his heart to a woman who's unable to offer hers.
