Sadie Ryder, single mother and physical therapist, has only one desire in life: to be the best mom she can. She knows there aren't many men willing to date a single mom, so she remains hopelessly devoted to the one man that will always love her: her five year-old son, Noah. Ty Sampson has led a life of solitude as an expert hacker and resident tech guru. And he liked it that way. Until now. Watching three of his best friends pair off with their soulmates is enough to make Ty reconsider his choices and hope for a chance at love too. After many attempts, Ty finally gets Sadie to agree to a date, but the Darkness attacks and leaves Sadie with a million questions whizzing through her head. She distances herself and her son from the Soul Shifters to protect him, but she underestimates the strength of the evil force. To save her son, Sadie will have to turn to the only other man with a hold on her heart and trust him with her precious baby. Ty is no match for the Darkness on his own and he'll need to tap into the most powerful force on Earth if he hopes to save either of them.
