Earth's Reaper. Earth's Magic, #7

The sunderer of souls had his heart stolen. Thaddeus is half Grim Reaper with the power to take people's souls. As a child, his ability led to him having issues at school, as his strangeness made him a target for bullies-who never stood a chance when he got mad and let loose. Needless to say, his social life sucked. His best friend growing up? The ghost in the graveyard up the street. As for girlfriends? Only ever tried dating once and let's just say it didn't end well.
Upon his rescue from a lab where scientists forced him to use his ability, this loner tries to get through life without any trouble, but apparently Mother Earth has other plans. She's set him on a quest to find the person behind his creation and expects him to put an end to their experiments once and for all. The problem is finding the culprit. The decades-old trail is cold, unlike his super-hot female companion.
Must not give in to temptation. The last thing Thad needs is to lose control and accidentally steal her soul. It would help if she wouldn't tease and tempt at every turn. Fiona's convinced he won't hurt her, but he's afraid she'll end up screaming like the last woman he dared to touch. Thankfully, he's got the mission to concentrate on, which has now switched to rescue mission. The mastermind behind his birth has taken his mom hostage, and it's up to Thad to free her, but infiltrating the secret lab, with his ghostly sidekick and Fiona, leads to revelations that are almost too much to handle.
To prevail, he's going to have to do the impossible, but if he succeeds, he might finally have a chance at happiness.
